I 576 Classification of the B component is by Msn1998a
Lindroos (1985). Lnd1985
The image rotator was in an unknown state, so two possible theta
values are listed for the 2001.4030 observation - one for zenith up
and one for north up. Trn2008

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.)
