Time-Ordered Data (TOD) from the DMR covering the period 19 November 1989 to 29 December 1993 (i.e., the entire period during which observations were made) are available in native format. The contents and format of the TOD are described in the DMR Explanatory Supplement. The data are in daily files, each 5 MB in size.
