Sequencer Site SIRTF IOC Activity c. 2002

CAID: MIPS-911 Title: IOC Darks, 70 um
 
System: MIPS Principal: kgordon Deputy: 
Objective:   
Dark current and read noise measurements.
 
Description: 
point to the 70 micron dark position (#1) and
take dark measurements using the 10 sec Dark IER
and 10 sec read noise measurements using the
Read Noise IER.

Resources

Duration:   30 minutes
 
Real time downlink:   No   

Data Volume (uncompressed): 33.6 Mbits
 
List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Dark IERs: mips_drk70umA_10s35, mips_drk70umB_10s35, Read Noise IERs: mips_rn70umA_10s50, mips_rn70umB_10s50
 
List Analysis tools required (downlink):   DAT - mips_sloper, mips_caler, mips_enhancer

Outcome

Estimate of data turn around:   24 hours
 
Description: Create 70um dark current calibration image. Standard output of mips_enhancer. Determine read noise.
 
Can proceed in parallel with other activity: No
 
Must outcome be confirmed before next activity: No
 
Method of Confirmation:   Create dark current image. Check that the dark current was stable over the measurment. Create read noise measurement and compare to previous measurements.
 
 
Success criteria: Good dark current measurement. No weird behaviors (check ramps, stim latents, etc). Nominal read noise values.
 
Contingency plan:  It's a calibration frame. As long as any changes between calibration image are reasonable and understandable, things are fine. If not, then any problems need to be fixed so the next calibration image is taken correctly.

Additional Comments:
To be scheduled at the beginning of every campaign using the 70 um detectors but after start-up and warm-up activities after instrument checkout has reached a certain level.
