The file is composed of two parts - the first section is the format of the ASCII file, the second, the format of the binary file. The ASCII format file *.af must be renamed to *.afm to be used with the Freeform utility. Likewise, the binary format file *.bf must be renamed to *.bfm. The structure of this file is: Field 1: Variable name Field 2: First position of variable in line Field 3: Last position of variable in line Field 4: Type of variable Field 5: Precision of variable **Refer to Freeform user's manual for further information See format file libya.fmt in this directory ==================================== ======================================================== Sample Data A representative sample of data records showing the first 10 lines and the last 10 lines of the ASCII data file(i.e. the .dat file).

If you use, need, produce, handle, archive, or are concerned with or about earth-science data sets, your participation in the EDBS is solicited. Please note that government regulations require prepayment on all orders. Telephone requests will be accepted, but data cannot be shipped until payment is received. The EARTHQUAKE DATA BASE SYSTEM consists of three data bases; this section of the documentation presents information for the Multi-Catalog Historical Earthquake Data Base. For more information about the US or INT Data Bases, contact Glen Reagor (address and telephone number is at the top of this page). ======================================================== ======================================================== END OF DOCUMENTATION FILE ======================================================== ======================================================== +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ NOTE: This is a partial documentation of the USGS format The full format can be seen in the file: /data/usgs/gsform.txt or as a series of *.pcx files in the directory: /data/usgs on the North American CD-ROM or on the Global Catalog CD-ROM. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ END OF DOCUMENT FILE =============================================================
