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).
