#	data file holding info on observatory position.
#	format is:
#	# in col 1 is a comment 
#	1.observatory atronomical lat in deg(int), min(int), sec(float)
#	2.observatory west longitude  int hour, min,secs(float)
#       put lattitude on one line as 3 numbers (separated by spaces).
#	put west longitude on following line  3 numbers per line.
#	any characters after the 3 numbers on a line will be ignored..
#	it's ok to put comments between the two lines.. just make sure
#	lattitude preceeds west longitude.
#
#  notes: 
#	   1. geocentric long is the same as geodetic long.
