Description
The selectband function filters the data so that only some of
it is copied to the output measurement set.
This function selects input records where any of the correlations
are within one of the eight standard VLA observing bands. These
bands are:
| Band |
Frequencies |
| 4 |
48 - 96 MHz |
| P |
298 - 345 MHz |
| L |
1.15 - 1.75 GHz |
| C |
4.2 - 5.1 GHz |
| X |
6.8 - 9.6 GHz |
| U |
13.5 - 16.3 GHz |
| K |
20.8 - 25.8 GHz |
| Q |
38.0 - 51.0 GHz |
The input argument to this function is a single character, case
insensitive, string containing one of the band codes shown
above. This is then translated to the relevant frequencies and
passed to the selectfrequency function described above. Like the
selectfrequency function this function may also copy data that is
outside the band if some of the data in an input record is inside
the specified band.
If the input parameter is unset then no frequency selection is
done. This is the default.
This functions returns F if the selection could not be done.
