Mine a seismic data base to extract secions of time limited data
Mine.seis(at1, at2, DB, grepsta, grepcomp, kind = 1)
at1 |
time 1 in julian days |
at2 |
time 2 in julian days |
DB |
data base structure to searcth through that provides the files where data is to extracted from |
grepsta |
which stations to extract |
grepcomp |
which components to extract |
kind |
kind of data, segy=1, sac=2 |
The data base is a list or dataframe containing the files names, the beginning time (t1) and ending time (t2) for each file in the data base. Mine.seis uses grep on the file names to extract specific files from the DB list.
list of seismograms cut from the database
The headers in the digital (segy or SAC) data files may not necessarily match the file names. Note that program JGET.seis extracts the station name and component name from the digital header and does not use the file name. It may be prudent to force the file names and header files to match prior to using Mine.seis. For SEGY files, in LINUX-UNIX, use: rename, segymod (PASSCAL) to modify the headers
