FOCAS Bonus Fields II
We have selected 6 arcminutes x 6 arcminutes fields which include
three and more >13 V mag. Landolt's photometric standard stars around +50 deg declination.
Reference is Landolt 2013, AJ, 146, 131.
Sometimes 13mag stars are too bright, and 14mag stars are more suitable.
Pointing information: When FOCAS is at PA=0 degree, i.e. chip 2 of
FOCAS is at north,
chip1 is at south. When pointing FOCAS with the setupfield command
to the coordinates shown in the list, without
any offset, you will find the same CCD image with the charts.
All Landolt's photometric standard data in Landot 2013 are
here.
