| Title: | MIPS first light | ||
| Objective: | To determine if the MIPS arrays are responding to illumination through the telescope. | ||
| Description: | Place a bright star in the FOV of each array. Execute the photometry AOT for each array. For the 160 mm array we may | ||
| have to execute the photometry AOT several times (up to 3) with different scan mirror offsets to ensure the source is in the FOV. | |||
| Place in Schedule: | After dust cover off | ||
| Required Conditions: | S/C pointing understood to 1' (TBR) and stable to 0.5" in 500 sec (TBR). | ||
| For 24um, the backgrd radiance must be less than 7.0E-9 W/cm2/sr (< 45K). | |||
| For 70um, the backgrd radiance must be less than 3.1E-10 W/cm2/sr (< 17 K). | |||
| For 160um, the backgrd radiance must be less than 2.6E-11 W/cm2/sr (< 8 K). | |||
| Need suitable star in the OPZ. Observable candidates for 70 & 160 mm arrays are e Car and a Boo. | |||
| Need a fainter star, such as b Leo, for 24 mm. | |||
| Resources: | |||
| duration (best estimate) | 5 min for each array x 4 = 20 min | ||
| real time downlink | preferably yes, especially for 160 mm | ||
| special post event actions | No | ||
| Outcome: | |||
| description | Photometry maps of stars | ||
| can proceed in parallel with other activity | No, dedicated observing | ||
| must outcome be confirmed before next event / test /activity | Must be confirmed before further MIPS operations | ||
| method of confirmation (sensor TLM, data analysis, etc.) | Data analysis | ||
| estimate of data turn around if required for confirmation | < 24 hours | ||
| Unique or included in planned uplink or downlink/analysis tool | AOTs | ||
| Contingency Plan: | Repeat, changing S/C, scan mirror offsets. Use fainter source if necessary. | ||
