WDS 21079+3324 TRN 31 : NOTES
 
 
discov_num notes refcode
TRN 31 The image rotator was in an unknown state, so two possible theta
values are listed for the 2001.7367 observation - one for zenith up
and one for north up. However, the 2MASS measure effectively rules
out one option. Trn2008
HD 201345 Aslanov et al. (1984 SvAL 10, 278) discuss the radial velocities and
the possibility of a low-mass companion. Msn1998a

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.)
