COMBINE

 

A program to combine two i.out files generated by RAYINVR in two separate runs into one file of the same format for use by DMPLSTSQR

Files

Input file: i1.in is the output file i.out generated by RAYINVR

Input file: i2.in is the output file i.out generated by RAYINVR

Output file: i.out contains the combined information in the files 
   i1.in and i2.in in  the same format  for use as input  to the 
   program DMPLSTSQR

The files i1.in  and i2.in  must have been  generated by  RAYINVR 
using the same velocity model  with the same parameters  selected 
for inversion in both runs. COMBINE may be used if,  for example, 
the rays from two  or more shots are  traced in separate runs  of 
RAYINVR. Note, COMBINE should not be used if  partial derivatives 
for the same travel time picks have been calculated in both of the 
separate runs since two  ray paths may  be used in the  inversion 
corresponding to a single  travel time pick,  instead of the  ray 
path with minimum travel time.
