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. BAND1_12MU.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). BAND2_25MU.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). BAND3_60MU.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). BAND4_100MU.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). Modification History : In Feb. 2002 this data set was reviewed internally as part of a general inventory review and upgrade. At that time in addition to minor format editing the following changes were made to the label files: - The names of the filter files were changed to reflect the band number and center wavelength. These changes were propagated to this file as well. - The PRODUCT_NAME field was modified to include the name of the spacecraft. The associated catalog files, including this one, were upgraded to current standards at the same time.

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.
