| CAID: MIPS-918 | Title: 70 um IC - routine, Phot AOR | |
| System: MIPS | Principal: aalonso | Deputy: dfrayer |
| Objective: | To obtain IOC acceptable 70um photometry illumination correction to be obtained on a regular basis. This activity is a companion to the 70 um Scan ROUTINE Phot AOR. The pair of activities will allow us to determine the relative efficiency and quality of illumination corrections created using scan and photometry AORs. |
| Description: | A 3x3 square dither map (1 cycle) will be obtained with 3 second DCEs in a region of the sky chosen to avoid bright point sources. The offsets are 300 arcseconds. At each position there will be 12 images, so a total of 108 images will be produced each time this task is excecuted. The map will require about 21.0 minutes of observing time. |
| Day: 45.6909722222263 | Suggested Order: | ||
| Must be preceded by these activities (list by CAID): MIPS-322 | |||
| Place in Schedule: Start of each campaign that requires illumination corrections at 70um. Telescope temperature stable and appropriate for 70um. MIPS temperature stable. CSMM operational. | |||
| Priority: Critical | |||
Conditions | |||
| Maximum telescope temperature: | 12 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: | 3 arcsec (1 sigma radial) | ||
| Maximum precision offset uncertainty: | 1 arcsec (1 sigma radial) | ||
| Observatory configuration: | standard | ||
| Go/No Go criteria: | CSMM, CE, and stims and detectors must be operational, instrument and telescope temperatures must be stable | ||
Duration: 21 minutes
| | Real time downlink:
No | | |||
| Data Volume (uncompressed): 119.6 Mbits | |||
| List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Use phot mode AORs | |||
| List Analysis tools required (downlink): pipeline software | |||
| Estimate of data turn around: 24 hours | |||
| Description: A 70um IC to be used in photometry mode. | |||
| Can proceed in parallel with other activity: No | |||
| Must outcome be confirmed before next activity: No | |||
| Method of Confirmation: data analysis | |||
| Success criteria: Flats/I.C.s display no noticeable source residuals, have good S/N. Flattened/I.C.d FPS and AOT validation data sets have source signal independent of position in image. | |||
