To run chk_gaps:
NOTE: The SWAN OBT jumps every few months and you'll see a gap in their
data. Check the files in /ftp/tlm_files/SWASC and verify the timing glitch by looking at the science
data files. Email Patty, Luis, George and SWAN about the problem but take no action.
NOTE: During Keyholes be sure to cross check the gap times with the DSN schedule and the Keyhole schedule online at http://sohowww.nascom.nasa.gov/soc/keyholes.html or here to see which data set we are in (VGM, VGMF, VGMFL5, VGMFL6, etc) so all data gaps can be accounted for.
NOTE: To see what is in the telemetry file, type tlmtool -f filename
