| CAID: MIPS-916 | Title: 160 um IC - routine, Scan AOR | |
| System: MIPS | Principal: aalonso | Deputy: dfrayer |
| Objective: | To obtain IOC acceptable 160 um scan illumination correction to be used on a regular basis. This particular flat has a celestial coordinate appropriate for 160 um. If MIPS-914 or MIPS-195 are adequate at 160 um as well as at 24um and 70um respectively,then this task may not be needed. This activity is a companion to the 160 um IC ROUTINE Phot AOR. The pair of activities will allow us to determine the relative efficiency and quality of flatfields created using scan and photometry AORs. |
| Description: | A 2 degree long (1 leg) scan map will be obtained using the fast-scan AOT in a region of the sky chosen to avoid bright point sources. This will produce a total of 118 images to be median combined to produce a 160 um IC. The map will require about 12.7 minutes of observing time. It will be necessary to check the quality of the 160um IC as when the data are taken in fast mode a filled map is not produced in a single pass. If this introduces artifacts, it may be necessary to repeat the IC at medium scan rate. |
