The luminosity corresponding to the data referenced in a D0DAD file is computed using the standard luminosity utilities GET_FILE_LUM. To use these utilities, the run numbers used in producing the stream must be known. The file D0$DATA$D0DAD:RUN1B_MDS.FILECAT is an ASCII file containing a list of the files used to produce the master catalog. The first line of this file is a header, and the remaining lines are the list of files. This file can be copied and editted to produce the list needed by the luminosity utilities. Each file-entry line contains four fields. The first field is the Zebra file name and is all that is needed to get the luminosity. A file is put in the file catalog even if no events are selected into D0DAD files, so the file catalog contains the complete list of Zebra files.
