| CAID: MIPS-353 | Title: MIPS 24um Red Cross Calibration | |
| System: MIPS | Principal: dhines | Deputy: cengelbracht, dfrayer, SStolovy |
| Objective: | Check cross calibration between MIPS 24um camera and IRS Long. Use same 24um target as IRS 191 |
| Description: | This task uses a standard photometry AOT at 24um to observe a red, non-variable AGN with no PAH features observed previously with ISO SWS. Repeated for check. |
| Day: 65.2083333333358 | Suggested Order: P200 | ||
| Must be preceded by these activities (list by CAID): MIPS-240, MIPS-350 | |||
| 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). Before final operational parameters are set and instrument tuning complete. | |||
| Priority: Necessary | |||
Conditions | |||
| Maximum telescope temperature: | 33 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: | 10 arcsec (1 sigma radial) | ||
| Maximum precision offset uncertainty: | 1.4 arcsec (1 sigma radial) | ||
| Observatory configuration: | standard | ||
| Go/No Go criteria: | CE, MIPS, CSMM all working as expected | ||
Duration: 24 minutes
| | Real time downlink:
No | | |||
| Data Volume (uncompressed): 10 Mbits | |||
| List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Standard pipeline and data analysis tools. MIPS Phot/SR AOT required | |||
| List Analysis tools required (downlink): MIPS pipeline; image analysis tools; telemetry analysis tools | |||
| Estimate of data turn around: 36 hours | |||
| Description: Derive a monochromatic flux density based on best calibration data and color correction | |||
| Can proceed in parallel with other activity: No | |||
| Must outcome be confirmed before next activity: No | |||
| Method of Confirmation: Compare against spectrum acquired by IRS (IRS-191) | |||
| Success criteria: Derived MIPS 24um monochromatic flux density = flux density at 24um measured by IRS. | |||
| Contingency plan: | |||

Additional Comments:
Check against spectral leak check data from MIPS 240. If no leak in MIPS 240, look at color correction and IRS calibration. Set caution flag for observers, and reobserve during routine calibration. | |||
