Quality Control and
Data Processing

Here is a list of the current FLAMES/Giraffe data types, their definition, description, function, and approximate frequency within the Calibration Plan (if applicable). The first four columns list the content of the FITS keys HIERARCH.ESO.DPR.CATG/TYPE/TECH and of HIERARCH.ESO.INS.MODE.

DPR.CATG	DPR.TYPE	DPR.TECH	INS.MODE	description	needed for science reduction?	frequency
SCIENCE	OBJECT,SimCal or OBJECT,OzPoz	MOS or IFU	MED, IFU, ARG	science exposure (with simultaneous calib fibres: SimCal, otherwise OzPoz)
ACQUISITION	ACQUISITION	OBJECT	IMAGE	FACQ acquisition image	no	with science
CALIB	BIAS	IMAGE		bias	yes	daily
CALIB	DARK	IMAGE		dark exposure	no	monthly
CALIB	LAMP,FLAT	MOS or IFU	MED, IFU, ARG	standard flat lamp exposure with robotic calibration unit	yes	daily
CALIB	LAMP,FLAT,NASMYTH	MOS or IFU	MED, IFU, ARG	flat lamp exposure with Nasmyth screen (not regularly done, better illumination)	yes	for IFU and ARG
CALIB	LAMP,WAVE	MOS or IFU	MED, IFU, ARG	arc lamp exposure	yes	daily
CALIB	STD,SimCal or STD,OzPoz	[MOS or] IFU	[MED, IFU,] ARG	standard star exposure (with/without simultaneous calib fibres: SimCal/OzPoz); routinely taken only for ARG	no	daily
CALIB	SIMLAMP,TAL	MOS or IFU	MED, IFU, ARG	simultaneous calibration fibres only, arclamp (health check)	no	daily
CALIB	LAMP,FLAT	IMAGE		flat lamp exposure without fibre system (technical)	no	monthly
