This data set, prepared at NSSDC, indexes the ISIS 2 ionograms (data sets 71-024A-01A, -02A, and -10A) by station pass. The data are on an ASCII magnetic tape written on a MODCOMP IV computer. Information in the data set includes ionogram quality, telemetry station, stop and start data for the pass (times and locations), location at which the original telemetry tapes are stored, and experiment mode of operation. Some information relating to investigations 71-024A-02, -03, and -10 is also included since these investigations are closely related to the sounder operation; e.g., the value of the fixed frequency used is given, the presence of AGC trace is noted, and VLF operation is indicated. This index was prepared from an inventory of film received. The data can be provided on hardcopy or on microfilm, sorted according to time or station and time.
