Special Remarks:
Needs extra FF frames during daytime - whole programme requires only 1.6h
Abstract for MTS:
Observations of 4 very bright targets (V=1-3mag): 2 OBs for each target (one using
B346 and one Dic1_390+580). All OBs can be executed at the end of twilight. No FC submitted because of brightness of targets; however, please note that brightest 2 targets are binaries: the science target to be observed is always the brighter component.
Requirements:
1. do not execute OBs with seeing better than 0.7" (because of saturation)
2. some orders may still saturate: this is acceptable if the following regions
are not affected: 300-330nm of the B346 frames, around 390nm and 590nm for the
Dic1 frames - these are the regions they are interested in
3. extra daytime calibrations needed (by tweaking the total number of FF frames
in the CalobBuild), approved by PSO if daytime activities allow the extra load :
at least 20 D2 flats (best would be 40) if any of the *_blue OBs has been executed
during the night, and at least 20 (best would be 40) FF for the 390+580 setting if
any of the *_dic OBs has been executed (cf README for more info).
NOTE: the total execution time of the programme is only 1.6h, hence this extra
load of calibrations can be confined to just one day. PI also said that if OBs
were spread over 2/3 consecutive nights, the extra load of calibrations may be
taken only on one night!
