The units in the uncompressed exposure maps are seconds of time. The FITS files may be displayed using any data display package which accepts FITS data. To save space, these maps have been compressed using the Unix compress facility. These GIF images are provided to allow a quick look at the data. In order to determine observed counts, analysis of the FITS data is necessary.
Users can uncompress the data automatically when ftp'ing.
After transfer, the data need to be uncompressed using the gzip or compress utilities. In particular we thank J. Behnke, C. Cheung and G. Bimson for their unflagging support. Software to update the headers of the images processed at MPE with the AIPS-style WCS keywords was provided by P. Tyler. This help was most appreciated.
