>> How to plot YB6 stars in Guide is detailed.
>>
>> _Background_
>>
>> There's a certain amount of fascination with the NOMAD catalogue
>> amongst some. For Guide users most of NOMAD is already available, as
>> the USNO B1.0, UCAC2 and 2MASS data are already downloadable and
>> plottable in Guide, whilst Guide already has Tycho2 and Hipparcos
>> within it (and some also have the full UCAC2). So the use of NOMAD
>> tends to double up what already exists in Guide, and it carries no
>> particular extra information to that included in the other catalogues.
>>
>> But the YB6 is in NOMAD, and this seems to fascinate people for two
>> reasons. First, it is an unpublished USNO product which is
>> unavailable separately, so it only exists in NOMAD. This is still the
>> case, to some extent. However, it is a digitisation of the plates
>> from the Yale Proper Motion surveys, so anyone using the NPM1 and NPM2
>> (Northern PM 1 and 2 catalogues), and, the SPM2.0 or better still the
>> SPM3.3 (Southern PM version 2 or version 3.3) will already have access
>> to a lot of this data, although not all.
>>
>> Second, it carries 'V magnitudes'. In fact these are photographic
>> magnitudes taken through a yellow filter in much the same way 'quick
>> V' images have been taken by POSS (equatorially) and other surveys in
>> the past, and although they can be reasonable to around a quarter mag,
>> all the way down to magnitude 17, in crowded fields they are no better
>> than any GSC1.x or USNO A/B mag in terms of quality, being up to a
>> magnitude out.
>>
>> Nevertheless, if people can get at the data, they might no worry about
>> it so much, and not feel the need to access NOMAD whilst only
>> receiving mostly that which they've already got access to.
>>
>> Note also that many objects in NOMAD logged as unique to YB6 (ie not
>> in UCAC2 nor USNO B1.0) are also in 2MASS, but NOMAD uses all optical
>> catalogues if possible before resorting to using 2MASS positions
>> (although it will use 2MASS magnitudes wherever available), so
>> relatively very few truly unique YB6 objects will occur.
>>
>> _The Procedure_
>>
>> Ensure Guide is not running.
>>
>> With the latest upgrades of Guide 8 from the internet at
>> www.projectpluto.com it's now easy to access any dataset available via
>> VizieR. A little work is needed using a text editor, notepad will
>> likely suffice, but nothing clever is needed to be known.
>>
>> HOWEVER, three working files in Guide have to be added to in the text
>> editor, so for the seriously cautious, back up the files in you Guide
>> directory (there is no need to back up the subdirectories/subfolders,
>> just the files in the Guide directory/folder).
>>
>> Everyone else can simply backup, or make copies in a separate folder
>> elsewhere, or wherever, of the following three files which are going
>> to be modified :-
>>
>> download.txt
>> strings.dat
>> win_menu.dat
>>
>> download.txt will only exist if you have downloaded and used the later
>> upgrade versions of the program. If you haven't got it, you can't get
>> extra data from VizieR.
>>
>> After backing up those 3 files in whatever way load download.txt into
>> a text editor.
>>
>> The first few lines will look something like this, but will not carry
>> as many entries or be exactly like it:-
>>
>> # Documentation at bottom of file
>> 2798 -cI/305/out&-out.all=0 gsc23.dat
>> 2799 -cII/276/sdss5&-out.all=0&mode==1 sdssdr5.dat
>> 2800 -cII/270/catal tcs.dat
>> 2801 -cB/denis/denis denis.dat
>> 2802 -cI/297/out&r=Y yb6.dat
>> end
>>
>> Access for a new catalogue is entered as a line before the "end"
>> statement.
>>
>> In this instance I already have several catalogues that will be extra
>> to most, whilst not having several other catalogue retrieval routes in
>> the original because of having the full catalogues on hard disk (eg
>> ucac2 and cmc14).
>>
>> The running number in the first column is important, each entry must
>> have a unique number.
>>
>> In this instance the number chosen is 2802. Someone already having
>> gone past 2802 needs to pick the next number after their last entry.
>> Someone who hasn't gotten that far can use whatever number is next.
>>
>> This number must be remembered, it will be used elsewhere.
>>
>> In download.txt enter the line beginning 2802 exactly as shown, cut
>> and paste it if needed. Edit 2802 to be the number desired by your
>> system. If you have not as yet reached 2802, you can use 2802 even if
>> you have not used any of the immediately previous numbers, as long as
>> you never use it for something else in download.txt. ie, enter
>>
>> 2802 -cI/297/out&r=Y yb6.dat
>>
>> on the line immediately before the one saying "end", and change 2802
>> as desired.
>>
>> Now Guide knows whereabouts in VizieR to look for the data. It is
>> actually selecting the YB6 unique entries from NOMAD as per the above
>> URL segment.
>>
>> When it finds it, it will save it to a file in the Guide
>> directory/folder called
>>
>> yb6.dat
>>
>> which is an ascii file, a raw text file.
>>
>> Now we need to get Guide to do this action when we want.
>>
>> The toolbar could be used, but the YB6 unique objects (ie ones not in
>> UCAC2 nor USNO B1.0 nor 2MASS) are actually quite sparse (which is the
>> reason using all of NOMAD just to get the odd YB6 object is overkill).
>>
>> That's a bit of a waste of a toolbar button, which soon fill up the
>> menu bar if we're not careful.
>>
>> So, we'll add the invocation command to the menu under
>>
>> EXTRAS->Get Star Catalog Data
>>
>> If you run Guide now and look under that menu you will see there are

>> running before making and saving any further changes.
>>
>> Get YB6 from Internet will be added to the bottom of that list.
>>
>> Ensure win_menu.dat is safely backed up somehow, load it into a text
>> editor, and look down the file towards the end. As the menues go
>> right to left on screen, the entries in win_menu.dat are top to bottom
>> in the same order, more or less.
>>
>> You will eventually see some entries like
>>
>> 2550 1545 Get UCAC2 from Internet
>>
>> this is the group that is being looked for.
>>
>> Under the last entry of that group (although above Clear Ax.0 data if
>> that is the last entry) add the following line
>>
>> 2802 1563 Get YB6 from Internet
>>
>> This is where the 2802 comes in, this links to download.txt, when this
>> menu item is called, the same number action is run in download.txt...
>>
>> ...so IF YOU'VE USED SOMETHING OTHER THAN 2802 CHANGE THE ABOVE ENTRY
>> TO USE THE NUMBER YOU'VE USED.
>>
>> Now we have another slightly pedantic problem.
>>
>> In the above entry the second number column is the line number in
>> strings.dat where the text for this menu command also lives.
>>
>> It will likely not be 1563 on your machine. It will be very close to
>> that number, as not much extra is added to my strings.dat from normal.
>>
>> The end of strings.dat looks something like this (it will wordwrap,
>> all lines should star with [] )
>>
>> [] Anything following a [] is a comment. Comments can be added
>> freely at
>> []the end of this file, since GUIDE refers to strings by line number; no
>> []attempt is made to read past the last "meaningful" piece of text.
>> [] Most comments were added just to help translators figure out
>> where and
>> []how that text is used.
>> [] Lines 1026-1028 contain color values for planets; they are used

>>
>> with a linespace before them. The entry before this gap line is the
>> last in the menu. You will enter a new line after this, and it is the
>> number of that line you need to know for replacing the 1563 value in
>> win_menu.dat in the above example for adding YB6 to win_menu.dat.
>>
>> It's not as hard as it sounds. Most text editors and ascii viewers

>> just checked that, it works.
>>
>> The new line in strings.dat simply reads
>>
>> Get YB6 from Internet
>>
>> So now with the line
>>
>> 2802 1563 Get YB6 from Internet
>>
>> in win_menu.dat (with your number replacing 2802 from what you used in
>> download.txt and your line number from strings.dat replacing 1563)
>>
>> all are connected to each other.
>>
>> Now ensure Guide is not running still, and apply the above.
>>
>> From now on whenever Get YB6 from Internet is selected for any
>> reasonably small field YB6 stars will be added to the file YB6.dat in
>> the Guide directory/folder.
>>
>> Now all that is needed is to be able to view the data.
>>
>> Simply cut and paste the following data into a text editor and save it
>> as the file YB6.tdf in the Guide directory/folder.
>>
>> Now whenever you are in a field of two degrees or less and have
>> downloaded YB6 data, should any exist for that field, these will be
>> plotted as white stars to the V magnitude, or if there is no V
>> magnitude as small dotlike circles, where the B magnitude can be found
>> via right click (this should only occur for stars fainter then V mag
>> around 18 which are blue enough to be brighter in B mag so will be for
>> very faintest objects, so a small dot will suffice).
>>
>> Right click on these and the V mag (visual photographic plate mag, and
>> around +/- 0.3 mag at best, +/- 1+ at worst, especially in crowded
>> fields) and any B (blue photographic plate mag, ditto on quality, and
>> _not_ contemporaneous with the V mags) and any proper motion details
>> (not necessarily of the highest accuracy) are presented. More info
>> gives the RA and Dec quoted directly from the data in decimal degrees
>> (accuracy likely better than USNO B1.0 but probably never as good as
>> UCAC2, it's a photographic survey remember) and converted via Guide
>> into sexagesimal, as well as quoting the errors on the proper motion,
>> and repeating the rest of the right click data again.
>>
>> And that, as they say, is that. You can probably do it all in less
>> time than it takes to read this.
>>
>> Typical coverage is exemplified by a quarter degree field centred on
>> the sparse field around the cataclysmic variable AL Com. Only seven
>> stars are unique to YB6.
