Presumes mosaic has already been made in the output directory.<br />

b<br />

Approximate pixel size on images; mosaic pixel size is 0.6 arcsec.<br />

c<br />

Factor by which the PRF samples the data pixel size.<br />

d<br />

PRF normalization radius (input in Source Estimate block).<br />

e<br />

PRFs derived from cryogenic mission data.<br />

f<br />

Valid for most 24 micron data. Some fast scan maps may differ – a PRF derived from the data<br />

may be preferable.<br />
