CALBLOCK-REC-004: NISP LED flats¶
Observation configuration file¶
Scheduling¶
Once, after full thermal decontamination.
In case of failure, repeat at next possible opportunity.
Time-critical¶
No.
Dependencies¶
Must be executed after F-001 if scheduled back-to-back (to avoid persistence effects in the F-001 data).
Objective¶
Will take LED flats for master-flat creation and persistence monitoring. This calblock is a simple clone of the NISP part of CALBLOCK-F-007: VIS Nonlinearity, PTC, BFE and NISP LED flats.
Observations¶
30 LED flats for each LED, targeting 4 kADU fluence per exposure (90 e-/s LED flux). Afterwards, 4.5h of photo-MACC darks are taken for persistence decay.
NISP: Configure FWA = dark
for LED in [A, B, C, D, E]:
LED flux = 90 e-/s
Take 30 photo-MACC exposures
Take 30 MACC(15,16,11) darks for persistence decay.
