An OTW code to read a file of Ra,Dec (both floating point in dgeree units) and flag those stars that are positional repeats from earlier in the list unique positions. A positional match exists if the Ra,Dec residual is < SRAD arcseconds (where SRAD is an input argument). The only output is a filenamed "rd_repeats_flag.out" that flags repeats with a "1". All unique positions in the list are assigned "0".

  
% rd_repeats_flag.sh --help

Usage: rd_repeats_flag.sh LIST3 3.0 
arg1 - file listing Ra,Dec (both in units of degrees) 
arg2 - search radius for match in arcseconds
