| Title: | MIPS SED mode slit profile | ||
| Objective: | To determine the position and profile of the SED mode slit. | ||
| Description: | Place a bright star on the SED slit. Step the scan mirror in 1/2 pixel steps (5") for a total of 15 steps (75") while performing the SED | ||
| AOT after each step. Integrate for a total of about 2 min in each AOT. | |||
| Place in Schedule: | After dust cover off | ||
| Required Conditions: | S/C pointing understood to <5" (TBR) and stable to <0.5" (TBR) | ||
| For 70 um performance, the backgrd radiance must be less than 1.0E-12 W/cm2/sr (< 12 K). | |||
| Need bright stars in the OPZ. a Boo and e Car are possibilities for a December launch date. | |||
| Resources: | |||
| duration (best estimate) | 40 min | ||
| real time downlink | No | ||
| special post event actions | No | ||
| Outcome: | |||
| description | 1D map of SED slit and position of slit relative to PCRS. | ||
| can proceed in parallel with other activity | No, dedicated observing. | ||
| must outcome be confirmed before next event / test /activity | No, except yes before any further SED activities. | ||
| method of confirmation (sensor TLM, data analysis, etc.) | Data analysis | ||
| estimate of data turn around if required for confirmation | |||
| Unique or included in planned uplink or downlink/analysis tool | AOT and special IET | ||
| Contingency Plan: | Repeat, increasing range of scanning mirror and/or integration time. | ||

| Comments: | Since the SED mode will not be immediately released, this test can be delayed until after IOC. | ||
| Part of this test may be done in the Focal Plane survey. | |||
