| CAID: MIPS-210 | Title: 70 & 160 um latent images & saturation | |
| System: MIPS | Principal: hdole | Deputy: alberto |
| Objective: | Characterize the behavior of very bright (saturated) sources on the 70 and 160 micron arrays. |
| Description: | Point sources of which are 50%, 100% and 500% of the full will will be observed. Each point source will be observed using both photometry and scan map AOTs. Three sources are needed for each of the 2 Germanium arrays (70, and 160 microns). The goal of this task is to check the behavior of point sources as a function of how hard they saturate. The 50% well point sources are taken as a baseline for the 100% and 500% point sources. Outline of the Task: At 70um (for each of the three 70um sources = 3 different backgrounds): Construct a medium mode scan map including both forward and reverse scans. 2 scan legs at medium mode scan rate (forward and backward) 1 cycle of 10-second exposures using the Photmetry AOT at 70um. At 160um (for each of the three 160um sources = 3 different backgrounds): Construct a medium mode scan map including both forward and reverse scans. 2 scan legs at medium mode scan rate (forward and backward) 1 cycle of 10-second exposures using the Photmetry AOT at 160um. |
| Day: 77.4402777777868 | Suggested Order: R600 | ||
| Must be preceded by these activities (list by CAID): MIPS-246, MIPS-322, MIPS-324, MIPS-327 | |||
| Place in Schedule: This test should be done near the end of IOC as it is a pretty high level validation of the instrument. | |||
| Priority: Desired | |||
Conditions | |||
| Maximum telescope temperature: | 6 K | ||
| Minimum telescope temperature: | 5.5 K | ||
| Should activity be repeated if focus changes? | No Repeat if focus changes by 0 mm | ||
| Maximum absolute pointing uncertainty: | 1.4 arcsec (1 sigma radial) | ||
| Maximum precision offset uncertainty: | 1 arcsec (1 sigma radial) | ||
| Observatory configuration: | Standard | ||
| Go/No Go criteria: | Array temperatures must be stable, detectors must be functioning nominally | ||
Duration: 307 minutes
| | Real time downlink:
No | | |||
| Data Volume (uncompressed): 1261 Mbits | |||
| List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Photometry & Scan Map AOTs | |||
| List Analysis tools required (downlink): Standard MIPS data reduction pipeline | |||
| Estimate of data turn around: 72 hours | |||
| Description: Run data through pipeline. Examine the behavior of pixels after they have been saturated. This behavior will include both saturation and latent effects. The 50% point source will act as the control for the latent behavior. | |||
| Can proceed in parallel with other activity: No | |||
| Must outcome be confirmed before next activity: No | |||
| Method of Confirmation: data analysis | |||
| Success criteria: Good enough data to measure effects of saturation downstream from the saturation event. | |||
| Contingency plan: We might be able to investigate the behavior of saturation using regular mission data, but it will probably be difficult. | |||
