| Title: | MIPS Scan to Determine Confusion Limits | |||||||
| Objective: | Deep observations at 70 and 160 microns to estimate the MIPS confusion | |||||||
| limits at three galactic latitudes (low background, high, and intermediate). | ||||||||
| Description: | Acquire normal scan observations at 70 and 160 microns of three 5 arcmin X 0.5 degree fields | |||||||
| at, or near the galactic pole, the equator, and an intermediate position. | ||||||||
| Can be the same as: | Verify pipeline -- Scan | |||||||
| Three identical AORs executed at three different pointings: | ||||||||
| Slow scan rate, 0.5 degree leg length (full coverage), 4 up and back scan legs with minimum offset step | ||||||||
| Place in Schedule: | After CTA/instrument cool down and all other instrument testing is complete. | |||||||
| For 160 um performance, the backgrd radiance must be less than 5.2E-13 W/cm2/sr (< 6 K). | ||||||||
| Can be concurrent with other AOT/instrument tests. | ||||||||
| Required Conditions: | CTA and instrument at nominal operating temperature for the 160 um band (< 6 K). | |||||||
| PCS performance needs to be nominal in pointing, offsetting, and scan stability. | ||||||||
| Resources: | ||||||||
| duration (best estimate) | 2 hours | |||||||
| real time downlink (Y / N) | No | |||||||
| special post event actions (Y / N) | No | |||||||
| Outcome: | ||||||||
| description | Fully calibrated MIPS scan data products in three bands. | |||||||
| can proceed in parallel with other activity | No - dedicated observing | |||||||
| must outcome be confirmed before next event / test /activity | No | |||||||
| method of confirmation (sensor TLM, data analysis, etc.) | Data analysis | |||||||
| estimate of data turn around if required for confirmation | 7 days | |||||||
| Unique or included in planned uplink or downlink/analysis tool | Standard pipeline system and standard data analysis tools required. | |||||||
| MIPS scan AOT required for uplink. | ||||||||
| Contingency Plan: | ||||||||
| "What if..." | Revisit pipeline and/or AOT design depending on the nature of a failure. | |||||||
| IOC Critical | No | |||||||
