DESCRIPTION

The guralplocate program parses a series of log files from a Guralp data logger written to a series of output files by the SCREAM program or from a data dump from a SAM unit. From these files it extracts lines in the log file containing latitude and longitude information. It reads all these numbers into memory and computes the following statistical estimates of the distribution of numbers: mean, median, lower quartile, upper quartile, lower bound, upper bound, and the number of samples in the ensemble. The statistics are sent to standard output with labels defining the results for the latitude and longitude.

BUGS AND CAVEATS

The method used to find the GPS fix data is crude and depends upon a fixed format line written into the log file. If Guralp changes the format of the GPS fix lines in this log file it will not work. The algorithm is crude like old FORTRAN fixed format reads.
