Contents
- rawX, rawY
- pixel coordinates: these are used for the
offset correction with the dark frame by using CAL_rgsGetDarkFrame
- NODEID
- (optional array): if present, it has the same
length as the rawX, rawY pairs, and it overwrites the state
variable ccdNodeId
- PHA
- (integer): PHA
- time
- event time coordinates in the TIMCOORD time frame
(see section 2.2)
- SHAPE
- number of pixels combined during
on-board split event reconstruction
- FPA_temp
- temperature of the focal plane assembly; this
affects the temperature of the readout electronics.
- CSG_ID
- clock sequence ID (stored as CCDCSG in the
ODF); this will be passed on to CAL_rgsGetDarkFrame
Notes
- Aging of the electronics will be implemented by updating of the
CCF constituents ADUConv & DarkFrame
- This CAL routine may also require a dependency on the satellite
pointing direction, should a known offset distribution be required
to be calculated as a function of SUN aspect angle and/or other
bright objects in the FoV (planets).
