When you print a column of data (GHA and Dec) for your selected time interval, we have noted that there is a display error when the declination changes from North to South or vice versa. This should change labels when the declination is 0° 0' but our code has a bug in it so it changes the label when just the degrees part goes to less than zero. So you might get a display like this

code:
3/18/2007 : 09:00: 312° 57.0'  S001° 02.5'  002° 24.1'  310° 32.8'  000° 16.1'  000° 00.1'       
3/18/2007 : 10:00: 327° 57.1' S001° 01.5' 002° 21.9' 325° 35.3' 000° 16.1' 000° 00.1'
3/18/2007 : 11:00: 342° 57.3' S001° 00.5' 002° 19.6' 340° 37.7' 000° 16.1' 000° 00.1'
3/18/2007 : 12:00: 357° 57.5' N000° 59.5' 002° 17.3' 355° 40.2' 000° 16.1' 000° 00.1'
3/18/2007 : 13:00: 012° 57.7' N000° 58.5' 002° 15.0' 010° 42.7' 000° 16.1' 000° 00.1'
3/18/2007 : 14:00: 027° 57.9' N000° 57.5' 002° 12.7' 025° 45.1' 000° 16.1' 000° 00.1'
3/18/2007 : 15:00: 042° 58.0' N000° 56.5' 002° 10.4' 040° 47.6' 000° 16.1' 000° 00.1'
3/18/2007 : 16:00: 057° 58.2' N000° 55.6' 002° 08.2' 055° 50.1' 000° 16.1' 000° 00.1'
3/18/2007 : 17:00: 072° 58.4' N000° 54.6' 002° 05.9' 070° 52.5' 000° 16.1' 000° 00.1'
3/18/2007 : 18:00: 087° 58.6' N000° 53.6' 002° 03.6' 085° 55.0' 000° 16.1' 000° 00.1'

Please note that in cases like this the last few declinations are actually south, although still showing up as north in the print out.

The actual displayed output in the program remains correct, this is just an artifact of the print routine.
