wblod
wblod is a miriad task which
converts the raw rpfits files from the wb correlator and converts the
data into miriad format. The conversion process required wblod to be
run twice (to allow corrections for antenna positions etc). A perl
wrapper wblod-wpass.pl makes this transparent to the user. This wrapper
takes the name of the rpfits file to convert and writes the output
miriad file into the current directory. You do not need to specify the
directry the rpfits file is in, this is added automatically. Typical
usage would look like:
> source
/DATA/KAPUTAR_2/at20g/at20g_setup.csh
> cd /DATA/KAPUTAR_2/at20g/data/region-50-60
> wblod-2pass.pl 2005-09-11_2019.C1049

A small number of warnings (such
as in the example) is to be expected. You should check the number of
flagged spectra is low.
