abssbkg - tpcclib 0.8.0 © 2023 by Turku PET Centre

Subtract constant background radioactivity in on-line blood sampler data.
The average of coincidence cps from 0 to specified time is calculated
and subtracted from the data; in case of Scanditronics/GEMS this is
a separate process for the two detector pairs, and in case of Allogg
separate for the two channels.
The background radioactivity is assumed to be stable during the assay
(not decaying); do not use this program in case of momentary background
radiation.
Notice that the original data file is overwritten by default.
 
Usage: abssbkg [options] abssfile time
 
Options:
 -o=<filename>
     Name for corrected file; by default the original file is overwritten.
 --dry
     Dry run: background is shown but data is not changed.
 -h, --help
     Display usage information on standard output and exit.
 -v, --version
     Display version and compile information on standard output and exit.
 -d[n], --debug[=n], --verbose[=n]
     Set the level (n) of debugging messages and listings.
 -q, --quiet
     Suppress displaying normal results on standard output.
 -s, --silent
     Suppress displaying anything except errors.
 
Example 1: calculate background from 0-60 s and subtract it.
     abssbkg -o=us1328_corr.bld us1328.bld 60
Example 2: calculate mean radioactivity [cps] from the measurement.
     abssbkg --dry us1328.bld 999999
