I find that, say for the iss, the mag value given is different when I use a tle file with no mag
data, along with the above way to get the mag data, then if I use mike's file which has mag data.
They should be the same value of mag, as they use the same mag info to compute the magnitude value
of the iss. I am missing something

Remember that in one respect, UCAC-2 differs from the other downloadable datasets: it doesn't
cover the entire sky. Most areas north of about declination +40 lack UCAC-2 data.
From what I can tell, it now cover's the whole sky. I could be wrong.

Also I don't know why I thought the UTC was fixed in guide. I get UTC being off from EST. There's
a 5 hours difference in time zone, but the seconds value is off by 1 second it seems between them.
