returns bolometers to be measured in a SKYDIP SCULIB_SKYDIP_BOLS
Only those sub-instruments that are looking out through a suitable filter will be measured. Thus, if the filter in front of the SHORT array is ’350’ or ’450’ the returned string will contain the word SHORT_DC. Other filter/sub/bolometer combinations are as follows:-
600 or 750 or 850 in front of the LONG array gives LONG_DC
1100 in front of the P1100 photometer gives P1100_DC
1300 in front of the P1300 photometer gives P1300_DC
2000 in front of the P2000 photometer gives P2000_DC
The returned BOLOMETERS string will contain the words for each sub-instrument to be measured separated by commas.
