The p_test algorithm is a filter which reads the *.sheet.p files and outputs
corresponding *.pf phase pick files and *.af amplitude files which are input data for the he_relp location algorithm.

To compile p_test, invoke:

make p_test

To run p_test, invoke:

p_test sheet_file 

where sheet_file is the transcribed file from the original reading/analysis
sheets (ie: 500720.2056.sheet.p).

For each event, p_test reads the file containing the transcribed
reading/analysis sheet data and outputs the corresponding phase pick and
amplitude files read as input by he_relp.

Sample p_test I/O files for the 500720.2056 event are included in this 
directory.
