Detailed Description

This program reads in binary SFTs and writes out narrow-banded merged SFTs.

Revision splitSFTs.c,v 1.41 2008/10/29 16:54:13 was reviewed by the LSC CW Review Committee Thur Oct 30, 2008

Suggested improvements: issue warning at ambiguous frequency values that are so close to the boundary of a bin that rounding might end up giving an unintended bin check for consistency of input SFTs (same timebase, ascending timestamps etc., see spec) and merged SFTs (check last header of a file we are appending to)

Other possible improvements not suggested by the committee keep output files open (if there aren't too many) obscure a mystery factor in command-line record even if given with long option –factor
