| Title: | MIPS Off-axis Glints | ||||||||
| Objective: | Search for scattered light and glints from stars out of the field-of-view. | ||||||||
| This tests the sky observing paths rather than contamination of MIPS darks (see othe scattered light proposal for that). | |||||||||
| Description: | |||||||||
| including flow / state diagram | Using an extremely bright source like IRC+10216 or equivalent, take 4 scans | ||||||||
| beginning ~5" outside the field of view and extending to 3 degrees away. | |||||||||
| Use the medium scan mode (40-second per point). | |||||||||
| Place in Schedule: | After aperture door is opened. | ||||||||
| (relative to water shed events) | |||||||||
| Required Conditions: | Telescope must be fully cold at 5.5K. | ||||||||
| Basic MIPS functionality must have been confirmed. | |||||||||
| Resources: | |||||||||
| duration (best estimate) | 15 hrs | ||||||||
| real time downlink (Y / N) | no | ||||||||
| special post event actions (Y / N) | no | ||||||||
| Outcome: | |||||||||
| description | Any operational constraints about bright objects just outside the field-of-view will be understood. | ||||||||
| can proceed in parallel with other activity | no, requires dedicated pointing. | ||||||||
| 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 | N/A | ||||||||
| Unique or included in planned AOT? | |||||||||
| Uses the scan map AOT. | |||||||||
| Contingency Plan: | |||||||||
| "What if..." | If test fails it should be repeated. | ||||||||
