NAME

bwsel - Select records based on their wideband bandwidth  

PERSON RESPONSIBLE

CATEGORIES

uv analysis  

DESCRIPTION

BWSEL is a MIRIAD task which selects data based on a requested bandwidth. Notice that if data is selected, ALL channel and wide band data are copied, not just the windows selected. Use UVCAT with select=win(N) instead, if you need to select only certain windows. If data has changing number of spectral windows (nspect) or has no channel data, program will skip copying those data with a warning.  

PARAMETERS

vis
The names of the input uv data sets. Multiple names can be given, separated by commas. At least one name must be given.
bw
A set of bandwidths, in MHz, in order for a record to be copied. Use a 0 if no match is needed. Multiple non-zero values need to be all matched, i.e. non-zero BW selections are logically ANDed. Default: all records.
slop
Fraction of frequency within which the bandwith should be to be selected. Default: 0.25
nspect
If set to non-zero, this will be forced to be the number of spectral windows required for copied records. This option was added to work around datasets where nspect was varying and the first record was wrong.
out
The name of the output uv data set. If none supplied, input dataset is scanned and reports bandwidths (in MHz) where the dataset changes.
