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. |

(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.) |
