Trn2008		(Note: For some observations the image derotator was in an unknown state. In these
Trn2008		cases the theta value is either left blank or two possible values are listed - one
Trn2008		for zenith up and one for north up. For unresolved objects, the listed rho value
Trn2008		is the FWHM of the corrected stellar PSF. Larger FWHM values are indicative of
Trn2008		poorer seeing and/or non-optimal AO system tuning.)
