 | Now that only half of the 70 micron array is working, how can I cover a field of about 5'x 5' using photometry mode? |  |
 | There is a paragraph in the SOM on this very topic. Now, the 70 micron large field fine pixel scale AOT by default covers a region about 2.5' x 1.25'. To cover a larger region, you need to use cluster mode targets to cover the area -- keep visualizing the |

| Generically for MIPS, how can I cover a field of about 5'x 5' using photometry mode? | |
| For all of the bands, you can do this via cluster-mode targets; for 24 and 160 (and eventually 70), you can do this via raster mapping. There is a raster map example and discussion in the current Spitzer Observer's Manual (SOM) that might help you. Raster |

| Can I control the rate or placement of stimulator flashes in the MIPS AOT? |  |
| No; the rate and placement of stim flashes in the MIPS AOT observational sequence is controlled by the SSC, and is rarely changed. |

|
| How come I can't make more than 20 cycles in a single photometry AOR? | |
| The maximum cycles for MIPS photometry is limited to 20, even though it's not close to the 3hr limit for an AOR. It's not totally arbitrary...it has to do with the logic of placing stim cycles in the photometry observing sequence -- it just gets more comp |

| Why can't I derive the 24 um saturation values in table 8.13 (from the SOM) by sticking either 0 or large background levels into table 8.14? | |
| Trying to compare Tables 8.13 and 8.14 is like comparing apples and oranges. The values for truly (ideal) cases are in Table 8.13. The formulae in Table 8.14 actually describe the general case, which includes a combination of point and background flux, so |

| How do I best get started with my MIPS data analysis, and how do I make sense of it all? | |
| You can get a quick understanding of the various features in your MIPS data by consulting the MIPS Data Features/Caveats page at http://ssc.spitzer.caltech.edu/mips/features.html. |

| How do I modify my FIF.tbl so that MOPEX makes my output mosaic the size of my choice? | |
| Here is an example FIF.tbl file, which is by default placed in your output directory by the MOPEX module Fiducial Image Frame.
