The bundle of mission-independent files contains three collections: Earth Orientation Parameter (EOP) products, tropospheric calibration (TRO) files, and DSN meteorological data (WEA) files. These files may be used to calibrate data acquired from any spacecraft or mission. Each EOP file describes rotation from a specific Earth-fixed reference frame to a specific inertial reference frame. EOP files come in two types. The 'long' file contains data from 1962 through the present to three months in the future (based on predictions) in 5-day steps. The 'short' file contains data from 9 months in the past to three months in the future (based on predictions) in one day steps. Because EOP files are used for navigation, pairs of long and short files are released every 2-3 days. For archival use and because of the considerable overlap, only files with end dates spaced by about six months are retained in the EOP collection. File sizes are about 1.3 MB for the long version and 30 kB for the short version. Each TRO file allows calculation of path delays caused by passage of radio signals through Earth's troposphere. TRO files are initialized for each month with predictions, then are updated weekly, until a final version for the month (with only data) is released early in the following month. Only the final file for each month is included in the TRO collection. A monthly file is about 150 kB. The TRO collection also includes a 'seasonal' file which contains seasonal global, complex, and antenna corrections that should be computed and added to the corrections derived from monthly files. The seasonal file is valid for 1972-2048 and has about 6kB. WEA files are cumulative during a calendar year; they are initialized with data from January 1 and are closed with data from December 31. There is one accumulating file for each of the three DSN complexes for each year; the file for one complex for a full year is about 1.2 MB. During any year, the latest accumulating WEA file will supersede any previous file for the same year with the final (365/366 days) file being the only one remaining as the next year begins. Only the final file will be retained in subsequent versions of the collection.
