maskdata

This utility will write out a masked dynamic spectra. It was originally based on PRESTO's prepdata, but modified to write out the masked dynamic spectra and stop.

Summary

The maskdata task is a copy of PRESTO's prepdata with one key addition. It writes a headerless SIGPROC filterbank file of the raw pulsar data with the rfi mask applied. This can then be used later in single pulse search or other searches.

Changes to PRESTO

New:

• $PRESTO/src/mask_data.c

Modified:

• $PRESTO/src/backend_common.c
• $PRESTO/include/backend_common.h
• $PRESTO/src/Makefile

mask_data.c

This is a copy of prepdata.c with all function calls to "read_psrdata()" changed to "read_psrdata_mask()". The definitions of these two functions are in backend_common.c.

backend_common.c

This contains the functions used for reading in pulsar data. The main change we make is to add "read_psrdata_mask()". This function is a copy of "read_psrdata()", but with a write step that writes the masked data to file. The only changes are for opening and writing this file. The file name is hard-coded as "raw_data_with_mask.fil".

backend_common.h

Added "read_psrdata_mask" to the header file.

Makefile

Needed to add a maskdata target in the Makefile. Also needed to add to list of binaries.
