NAME

chantrans -- translate relative RXTE PCA channels to absolute

USAGE

         chantrans -i "infile" -f "outfile" -c "Relative channel ranges" -h (help) -p (print out all channel information) or chantrans

DESCRIPTION

This is a script that queries the user for a series of relative channel values (beginning at 0) and translates them into their absolute channel values and store that into a file ready for input into SA(E)EXTRCT.

This script file is meant to allow the user to specify an input file, and output file, and a series of relative channel ranges (i.e., 0-16, 22, 28-50) and the script will read the CPIX keyword from the infile translate the specified relative channel ranges to their absolute channels ranges (e.g., given CPIXn = (0:22),(23~29), (30:51;2), (52:255), the output file would contain 0-16, 22, 32-64) and this value would be input in SA(E)EXTRCT as the "chint" value.

PARAMETERS (SWITCHES/FLAGS)

-i {file}

provide name of the spectral file input to FPLOT.

-f {file}

provide the name of an output file to contain the absolute channel range.

-c {Relative channel range}

Give a relative channel range in the form of "0-5, 16, 17-22, 50-128" (Note that these values can be read off of an FPLOT image of the spectrum).

-p

Print out relationship between relative channels and absolute channels.

EXAMPLES

         1. chantrans -i "sac.pha" -f "chint.out" -c "0-16, 22, 28-50"
         2. chantrans
