DATA_SET_DESCRIPTION 
Data Set Overview
    =================
      The IRAS Low-Resolution (0.5 degree in-scan) Zodiacal
      Observational History File (ZOHF) consists of the time-ordered
      IRAS survey data averaged into 1/2 X 1/2 degree rectangular
      pixels along with pointing and timing information, covering the
      entire mission.
 
 
      The data used in generating these files (Version 3) is not
      identical to that used in generating the 2 arcminute in-scan
      Medium Resolution ZOHF (Version 2).  An explanation of the
      differences in calibration between the two data sets and a
      statistical analysis of the differences in the resultant
      position and fluxes may be found in Oken et al.(1988) and
      Boulanger (1988).
 
 
      While generally characterized as being 1/2 x 1/2 degree pixels,
      the actual pixel dimensions (in arc-minutes) are as follows:
 
		     Band    Wavelength   In-Scan  Cross-Scan
		      1          12        30.8       28.4
		      2          25        30.8       30.3
		      3          60        30.8       28.5
                      4         100        30.8       30.5
 
      (Oken et al. 1988).
