WDS 17175-2746 TRN 24AB : NOTES
 
 
discov_num notes refcode
TRN 24 AB and AC: The image rotator was in an unknown state, so two possible
theta values are listed for the 2001.4959 observation - one for
zenith up and one for north up. Trn2008
HD 156212 Levato et al. (1988) find the radial velocities to be "probably Lev1988
variable", but since the total range in 11 measurements is 33 km/sec
we assign it to the "C" category. 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.)
