DESCRIPTION
This command lets you copy the values of any SAC header variable from one file in memory to all of the remaining files in memory. You can select which file you want to copy from.
EXAMPLES
Assume you are using PPK to mark several times in the header of a file called FILE1. You are using the header variables T3 and T4. To copy those same markers into files FILE2 and FILE3:
SAC> READ FILE1 SAC> PPK SAC> ... use cursor to mark times T3 and T4. SAC> READ MORE FILE2 FILE3 SAC> COPYHDR FROM 1 T3 T4In this next example, assume you have read in a large number of files and you want to copy the event location, EVLA and EVLO, from the file called ABC into all of the other headers. This can be easily done by referencing the file by name not number:
SAC> COPYHDR FROM ABC STLA STLO
HEADER CHANGES
Potentially all.
