| Title: | MIPS Slew State Validation | ||||||||
| Objective: | Verify that the baseline slew state for MIPS works and does what is planned. | ||||||||
| Description: | Place MIPS into nominal slew state and make several slews over regions of different brightness'. | ||||||||
| This will be done by taking observations of dark regions positioned on the sky such that the slew path is predetermined. | |||||||||
| In between slews make an observation of a dark region to look for slew artifacts. | |||||||||
| CTA and instrument should be a nominal operating temperature to allow detection of small effects. | |||||||||
| Place in Schedule: | After aperture door open | ||||||||
| After CTA/instrument cool down: | |||||||||
| For 24um, the backgrd radiance must be less than 1.0E-11 W/cm2/sr (< 30K). | |||||||||
| For 70um, the backgrd radiance must be less than 1.0E-12 W/cm2/sr (< 12 K). | |||||||||
| For 160um, the backgrd radiance must be less than 5.4E-13 W/cm2/sr (< 6 K). | |||||||||
| It may be possible to split this test into parts executed a different times based | |||||||||
| on telescope temperature, but mapping in all three bands is optimal use of time. | |||||||||
| Basic instrument commanding and functionality must have been confirmed. | |||||||||
| After initial Phot/SR AOT testing is complete. | |||||||||
| Before final operational parameters are set and instrument tuning complete. | |||||||||
| Required Conditions: | CTA and instrument at nominal operational temperature. | ||||||||
| PCS performance: | Minimal PCS peformance required. | ||||||||
| Resources: | |||||||||
| duration (best estimate) | 0.5 hrs | ||||||||
| real time downlink (Y / N) | No | ||||||||
| special post event actions (Y / N) | No | ||||||||
| Outcome: | |||||||||
| description | Several Phot/SR AOTs will be executed. Standard data produces will result. | ||||||||
| 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 | 48 hrs | ||||||||
| Unique or included in planned uplink or downlink/analysis tool | Standard pipeline and data analysis tools. | ||||||||
| MIPS Phot/SR AOT required | |||||||||
| Contingency Plan: | Revisit instrument state during slews. | ||||||||
| "What if..." | Consider different reset rates, or other options. | ||||||||
| IOC Critical | Yes | ||||||||
