| CAID: MIPS-326 | Title: 24 um Scan AOT Validation - preliminary | |
| System: MIPS | Principal: dlp | Deputy: mrieke |
| Objective: | To do a quick check of MIPS Scan AOT using the 24um channel. |
| Description: | Execute MIPS Scan AOT just to check that it is performing as expected. A Scan Map AOT at fast rate of 1 degree, back-and-forth without cross scan step. Tune IPP file as needed . |
| Day: 45.8638888888963 | Suggested Order: H200 | ||
| Must be preceded by these activities (list by CAID): MIPS-130 | |||
| 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). Location of MIPS apertures must be completed. Basic instrument commanding and functionality must have been confirmed. Before final operational parameters are set and instrument tuning complete. | |||
| Priority: Critical | |||
Conditions | |||
| Maximum telescope temperature: | 33 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: 18 minutes
| | Real time downlink:
No | | |||
| Data Volume (uncompressed): 26 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: A 24um scan map of one degree using fast scan rate. | |||
| 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. | |||
