remove_RFI.c :Combines filterbank files in a given directory and then removes RFI from data by simple SD threshold test.
*Prereqs (header files): *rand_num_generator.h for creating gaussian distributions to replace RFI with.
*filterbank.cpp for opening the original filterbank file and
adjusting header values and writing the new cleaned filterbank file.
*make_cmd : Make file to compile remove_RFI.c
*To run: Type ./remove_RFI.o in the directory where the filterbank files are. The macros at the top can be set to TRUE and FALSE accordingly depending on what needs to be done
removal.c :This is like remove_RFI.c except only removes RFI from a single file who's name must be manually edited in the code itself. Requires same header files as remove_RFI.c
create_fil-single.py :This is the RFI removal code/filterbank creation code that takes the raw binary data from Deepthi's acq data program, and converts it to filterbank format.
Three arguments need to be passed in when the program is called:
- The output filename
- The start channel for the filterbank file
- The end channel for the filterbank file
adc_snap_MOPG2.py :shows the output of the ADC
spectrum_monitor.py shows the output spectrum for the four Stokes parameters from the SNAP
