Re: [guide-user] 45P in 3 different locations?

Hi Pete....

The critical list is a stand-alone; the MPECsort program actually finds the categories within the listings of the MPC DOU and separates those for those who wish to concentrate on only one type of minor planet....checking all categories/groups allows all to be quickly downloaded, but not actually identified on the final sorted list that the user has selected as to which group the mixed minor planets belong.

The comet information is identical and is indeed downloaded for the listing, and CAN be individually downloaded as the "/Soft02Cmt.txt" file through the edit function for the comets, BUT when downloading the list by RA and DEC it puts the comets into the selected parameters of the user, but does NOT place them in the comets.dat file for exhibition on the GUIDE display.

Hi Clay,

Since the MPC no longer breaks out critical list asteroids I've relied completely on your MPEC Sort ver 4.1.0.4 program for this function. The website says the routine pulls down the following circulars: Amors, Unusual Minor Planets, PHAs, Atens & Apollos, Atira, Comets.

Question: Am I correct in assuming that somewhere in there it's got also got what used to be the asteroids on the critical list.

I don't use the Sort program report because with things like the moon, the Milky Way, and local horizon it's easier to just select directly from the updated Guide 9 (10 Dec 2015 version).

Question: what's the difference between the comets downloaded thru MPEC Sort and those in the Soft02Cmt.txt file? If both data sets are stored in Guide are there duplicates, and to which will Guide 9 version 4.1.0.4 defer?

As noted elsewhe re, every night before observing I reload the house computer Guide9 through MPEC Sort and use it for planning. And every night before observing I reload the observatory computer Guide 9 with the posted version of MPCORB.DAT. At this point it looks like I should also be loading both computers with the Soft02Cmt.txt file after renaming it Soft02Cm.txt.

I'm not highly automated and will typically handle the astrometry for one object at a time, waiting for enough movement to justify 3 observations before moving on to the next object. (Slews aren't accurate and I don't have automatic plate solve). Given all of the above, can you suggest a better approach for astrometry?

Your inputs are greatly appreciated.
