| Title: | MIPS SED mode wavelength calibration. | |||||
| Objective: | To confirm the wavelength calibration of the MIPS SED mode. | |||||
| Description: | Place an HII region with bright OIII lines (52 & 88 mm) on the SED mode slit. Execute the SED AOT. | |||||
| Place in Schedule: | After dust cover off. | |||||
| Required Conditions: | S/C pointing understood to <3" (TBR) and stable to 0.5" in 500 sec (TBR) | |||||
| For 70 um performance, the backgrd radiance must be less than 1.0E-12 W/cm2/sr (< 12 K). | ||||||
| Need suitable HII region in OPZ. Candidates for a December launch are NGC 7538A, NGC 3576, NGC 3603, G298.22-0.34 & 30 Dor. | ||||||
| Resources: | ||||||
| duration (best estimate) | 5 min per AOT execution. | |||||
| real time downlink | Preferably yes, to make sure that the source is centered on the SED mode slit. | |||||
| special post event actions | No | |||||
| Outcome: | ||||||
| description | Spectrum of HII region with bright lines at 52 & 88 mm. | |||||
| 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 | ||||||
| Unique or included in planned uplink or downlink/analysis tool | AOT | |||||
| Contingency Plan: | Repeat with another HII region , integrate longer. | |||||
