A new set of 1x1 flat and dark calibration files is needed for the iDK-20 in support of today's completion of RID 21725 (30 images):
a. Red flats, bin1. The last bin 1 red flats on the calibration website were taken almost 2.5 months ago on 12/20/23 (5 files) and 12/19 (5 files).
b. Green flats, bin 1. The last bin 1 green flats on the calibration website were taken on 12/20 (5 files) and 12/19 (5 files).
c. Blue flats, bin 1. The last bin 1 blue flats on the calibration website were taken on 12/21 (4 files), 12/20 (5 files) and 12/19 (5 files).
Prior to those, the next most recent bin 1 flats were taken in mid-November.
d. Dark files, 30 seconds, bin 1. The most recent bin1 dark frames at that exposure were taken on 1/14/2024, but there are only 3 of them.
Prior to those, 3 bin1 darks exposed for 30 seconds were taken on each of 12/19, 12/20 and 12/21 of 2023, but there are features in the January frames that aren't in the December images.
