If set to no, a simple average is generated. +If not flux calibrated, this parameter has no effect - a simple +sum is generated. +.le +.ih +DESCRIPTION +Every "subset" group of spectra will be accumulated and the sum will be +written as a new spectrum. For example, if the input string contains +100 spectra, and subset=2, then 50 new spectra will be created. Each +new spectrum will be the sum of the consecutive pairs in the original string. + +If there are insufficient spectra to complete a subset accumulation, +the sum is written out anyway and a warning printed. For example, +if the input string contains 23 spectra, and subset=4, there will be +6 new spectra created, but the last one will be based on only 3 spectra. + +Subset may be set to 1 to allow a copy operation although this is not +a very efficient way to do so. +.ih +EXAMPLES +The following three examples are those described above. + +.nf + cl> addsets nite1 2001-2100 + cl> addsets nite1 2001-2023 subset=4 + cl> addsets nite1 2001-2010 subset=1 output=nite2 \ + >>> start_rec=2001 +.fi +.ih +SEE ALSO +bswitch +.endhelp -- cgit
