| CAID: MIPS-285 | Title: Scan Map of Large Planetary Nebula or SNR | |
| System: MIPS | Principal: wlatter | Deputy: |
| Objective: | Initial validation of scan AOT. Verify scientific validity of MIPS Scan pipeline products Could be an ECO. |
| Description: | Acquire normal scan map observations of an available stellar remnant with large spatial extent. Slow scan rate, 30 arcminute square field, 5.0 arcmin leg offsets, 1 cycle, 6 legs. *Presently 2hrs* Can be the same as: Evaluate fully supported AOTs (MIPS Scan) |
| Day: 69.7173611111139 | Suggested Order: Q800 | ||
| Must be preceded by these activities (list by CAID): MIPS-326 | |||
| Place in Schedule: After aperture door open After CTA/instrument cool down and all other instrument testing is complete. For 160um, the backgrd radiance must be less than 5.4E-13 W/cm2/sr (< 6 - 7 K). After MIPS functionality testing is complete. Can be concurrent with other AOT/instrument tests. | |||
| Priority: Necessary | |||
Conditions | |||
| Maximum telescope temperature: | 6 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: | 1.4 arcsec (1 sigma radial) | ||
| Maximum precision offset uncertainty: | 0.4 arcsec (1 sigma radial) | ||
| Observatory configuration: | |||
| Go/No Go criteria: | |||
Duration: 125 minutes
| | Real time downlink:
No | | |||
| Data Volume (uncompressed): 160 Mbits | |||
| List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Standard pipeline system and standard data analysis tools required. MIPS Scan AOT required for uplink. | |||
| List Analysis tools required (downlink): Standard astronomical data processing tools. | |||
| Estimate of data turn around: 0 hours | |||
| Description: Fully calibrated MIPS scan map data products in three bands. | |||
| Can proceed in parallel with other activity: No | |||
| Must outcome be confirmed before next activity: No | |||
| Method of Confirmation: Data analysis | |||
| Success criteria: Nominal execution of instrument and S/C with no obvious command failures. Extreme solar activity can invalidate the data - determined through analysis. | |||
| Contingency plan: Revisit pipeline and/or AOT design depending on the nature of failure. | |||
