The online (=automatically produced) 70 microns mosaics may not be good enough to start analyzing for science right away, but they are good enough to quickly assess your data - did you see something bright or not? For an initial look at your data, use ds9 or your favorite image viewer to examine the on-line mosaics that came with your data.
unix% cd /where/you/unpacked_data/r5315584/ch1/pbcd/
Note that, unlike for 24 micron observations, there are no "non-prime" data here. However, under pipeline version S11 onward, there are two mosaics - filtered and unfiltered. No source is apparent at the center, but off-center, there seems to be one. For completeness, we note that there are no 160 microns mosaics at all, because this array was never "prime," so all of these data are ancillary.
25.3 Set up lists of filenames and namelist files in preparation to remosaic data
Lists that contain all of the BCDs, masks, and uncertainty files are needed as input to the mosaic.pl script.
unix% cd r5315584/ch2/bcd/
unix% ls *_bcd.fits > InputImageList.txt
unix% ls *bmask.fits > DmaskList.txt
unix% ls *bunc.fits > SigmaList.txt
unix% wc *.txt
unix% nedit cdf/mosaic_70um.nl
Here you don't need to worry about serendipitous data or the first frame effect. You might want to check the length of each file (wc *.txt) to be sure that each list has the same number of files. If you find that that file has a lot more lines than the others, the following is probably what happened. Because the filtered and unfiltered BCDs have similar filename extensions, be sure that you are only putting the unfiltered (or just the filtered) into the InputImageList.txt file.
Edit the namelist to reflect where your cal files are located -- be sure to use absolute pathnames!
