bfit - BSU program solves for interval velocity from pick times in headers (C-Language)
bfit [ -h | infile emin emax labl ]
Basic Seismic Utilities program solves for interval velocity using pick times in headers of a VSP (Vertical Seismic Profile) data set. The user specifies the depth interval to be analysed using the minimum and maximum elevations. A two character label is used to identify the well. C-Language Version.

EXAMPLE:
bfit w001.seg 900. 920. A1
File w001.seg is processed by bfit. The zone to be analysed extends from an elevation of +900 to +920 meters (presumably ground level is at an elevation above +920 meters. The analysis is labeled A1. A postscript file, bfit.ps, is generated, and shows the data points with a solid line indicating the calculated travel times for the solution velocity.
