more information. There is a separate Fatal Bit Pattern for each type of mask that is being<br />

used as input (i.e. for the DCE Status masks, the RMasks and the PMask).<br />

Rmask List File : The text file containing a list of outlier mask images. Usually this will<br />

be left blank, as the RMask images are created during the mosaicking process. This<br />

option allows you to specify a previously created list of RMask images as input on<br />

second and subsequent runs of the pipeline, to save having to re-generate them.<br />

Pmask FITS File: The permanently-damaged pixel mask for the detector. This is a<br />

single FITS image, flagging the permanently damaged pixels in the instrument arrays.<br />

These files are stored in the /cal/ directory. There is a single PMask for<br />

each of the MIPS and IRS channels, but the IRAC ones have changed with time. See the<br />

file /pmasks.README for information on which PMask is applicable to<br />

your data. Note that the date that the data were taken is given in the DATE_OBS header<br />

keyword (not DATE - this is the date the file was written).<br />

FIF file: The Fiducial Image Frame file (see §5.6.4). This is an optional input file, as it is<br />

often generated from the input data using the Fiducial Image Frame module. There are,<br />

however, a number of cases in which you might wish to use a user-specified FIF (e.g. if<br />

you are trying to match the field of view to the other data channels).<br />

DCE_STATUS_MASK_LIST = /masklist.txt<br />

DCE_Status_Mask_Fatal_BitPattern = 32544<br />

RMASK_LIST = /rmasklist.txt<br />
