Data Set Overview
=================
This data presented with this data set include
FPA.TAB - The IRAS Detector File which provides for each
detector of the focal plane array its operational status,
associated filter, location, dimension, sterradiance, and
readout time offset.
FILTER1.TAB - The transmission and response values given in this
table are to energy/wavelength and represent averages over
all of the IRAS detectors of Band 1 (12 microns).
FILTER2.TAB - The transmission and response values given in this
table are to energy/wavelength and represent averages over
all of the IRAS detectors of Band 2 (25 microns).
FILTER3.TAB - The transmission and response values given in this
table are to energy/wavelength and represent averages over
all of the IRAS detectors of Band 3 (60 microns).
FILTER4.TAB - The transmission and response values given in this
table are to energy/wavelength and represent averages over
all of the IRAS detectors of Band 4 (100 microns).

Review
======
FPA.TAB underwent peer review on March 24, 1997.
FILTER1.TAB, FILTER2.TAB, FILTER3.TAB, and FILTER4.TAB were peer
reviewed on April 26, 1993, and updated on March 24, 1997.
Focal Plane Model
-----------------
An explication of the focal plane model adopted here is given in
McCallon (1992) [MCCALLON1992].
Detector Spectral Response
--------------------------
The detector spectral response of the Ge:Ga detectors used at 100
microns was assumed to be the same as that of the 60 micron
detectors even though the material came from a different source.
Limits on out-of-band leaks, at short and long wavelengths, are
tabulated in Beichman et. al (1988) [BEICHMANETAL1988]. At 12 and
25 microns, these leaks effect the calibration by less than 0.02
percent. At 60 and 100 microns, the effect is less than 10
percent.
