PEP image filenames have the form

"program"_"field"_"band"_"type of file".DR1[".extension"].fits

Only the single extension Map images have the ".extension" section of the filename.
Multi-extension data cubes are also available but will not display well in the 
IRSA Viewer preview tool.

program = pep in most cases, pgh for the GOODS fields
field = the galaxy clusters observed by PEP are:
	A1689  A1835  A2218  A2219  A2390  A370  CL0024 MS0451  
	MS1054  MS1358 RXJ0152  RXJ13475
	The blank fields observed by PEP are:
	COSMOS  ECDFS  EGS  GOODSN  GOODSS  LH
band = either the wavelength in microns, or "blue", "green", or "red".
	"blue" = 70 microns, "green" = 100 microns, "red" = 160 microns
	Possible values for "band" are 70um, 100um, 160um, and for the 
	MS1054 and RXJ0152 fields also 250um, 350um, and 500um.
type of file = Map, Mask, or Residuals. The latter come in two types, 
	using blind extractions or 24 micron priors ("blind_Residuals.3sigma"
	and "priors_Residuals.3sigma" respectively).

extension = sci, err, or cov, for the science image, uncertainty map, 
	and coverage map, respectively.


Despite fine-tuning, Starfinder tends to overestimate the flux of sources at
the faintest flux levels.  A correction of this effect has already been applied to the released catalogs,
using the functions derived from simulations. Correction curves are provided in the
released data package, in case users would like to un-correct fluxes. Curves of the completeness and the
fraction of spurious sources as a function of flux are included as well.
