| CAID: MIPS-327 | Title: Scan AOT Validation - med speed | |
| System: MIPS | Principal: dlp | Deputy: alberto |
| Objective: | Explore MIPS Scan AOT parameter space and to validate Scan Map AOT in the three MIPS bands (24um, 70um and 160um), for a sample of scan lengths and scan rates. (using MIPS-325 as a guide). |
| Description: | Execute MIPS Scan AOTs for all available selectable parameters, or a sensible range. Not all scan lengths need be tested -- do minimum, maximum, and several intermediate. Can be the test same as: Select final operational parameters Tune IPP file as needed Several AORs will be constructed using each scan rate that will have : 1) one forward and reverse minimum length scan legs for each of four available offsets (all scan rates) 2) one forward and reverse maximum length scan legs for mimimum and maximum offsets (fast rate only) 3) one X six forward and reverse medium length scan legs at two of four available offsets (fast rate only) 4) do one instance of 1 for 3 cycles (slow rate only) |
| Day: 65.2291666666715 | Suggested Order: P300 | ||
| Must be preceded by these activities (list by CAID): MIPS-130, MIPS-132, MIPS-235, MIPS-326 | |||
| Place in Schedule: After aperture door open After CTA/instrument cool down: For 24um, the backgrd radiance must be less than 1.0E-11 W/cm2/sr (< 30K). For 70um, the backgrd radiance must be less than 1.0E-12 W/cm2/sr (< 12 K). For 160um, the backgrd radiance must be less than 5.4E-13 W/cm2/sr (< 6 K). Mapping in all three bands is optimal use of time. Location of MIPS apertures must be completed. Basic instrument commanding and functionality must have been confirmed. After initial Scan AOT testing is complete. Before final operational parameters are set and instrument tuning complete. | |||
| Priority: Necessary | |||
Conditions | |||
| Maximum telescope temperature: | 6.5 K | ||
| Minimum telescope temperature: | 5.5 K | ||
| Should activity be repeated if focus changes? | No Repeat if focus changes by 0 mm | ||
| Maximum absolute pointing uncertainty: | 10 arcsec (1 sigma radial) | ||
| Maximum precision offset uncertainty: | 1.4 arcsec (1 sigma radial) | ||
| Observatory configuration: | standard | ||
| Go/No Go criteria: | CE, arrays, CSMM working; scan rate synched to slew rate | ||
Duration: 300 minutes
| | Real time downlink:
No | | |||
| Data Volume (uncompressed): 1000 Mbits | |||
| List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Standard pipeline and data analysis tools. MIPS Scan AOT required | |||
| List Analysis tools required (downlink): Standard MIPS pipeline; image analysis tools; telemetry analysis tools | |||
| Estimate of data turn around: 24 hours | |||
| Description: Several scans at minimum, maximum, and intermediate lengths, each using all three scan rates. Also, several small maps of varying numbers of legs, cross scan offsets, and map cycles. | |||
| Can proceed in parallel with other activity: No | |||
| Must outcome be confirmed before next activity: No | |||
| Method of Confirmation: Data analysis will show whether CSMM goes where it is told at the same time as the spacecraft. | |||
| Success criteria: Data is completely downlinked. CSMM properly synched to slew. | |||
| Contingency plan: Revisit uplink sequence/command expansion, or AOT design. Revisit CSMM parameter space. Delays beginning of MIPS science observations. | |||
