Functions

dada2ms(→ str)

Wrapper around Stephen Bourke's dada2ms.

orca.wrapper.dada2ms.dada2ms(dada_file: str, out_ms: str, gaintable: str = None, addspw: bool = False) → str[source]

Wrapper around Stephen Bourke’s dada2ms. Optionally apply a gaintable (only gaintable of type bandpass has been tested). It will write a ms with the data in the DATA column. If the directory of the out_ms does not exist, it will create the directory.

Parameters:

dada_file – Path to the dada file.
out_ms – Path to the output measurement set.
gaintable – Path to the gaintable. Default is None which means don’t apply the calibration.
addspw – Use the –apend –addspw options.

Returns: Path to the output ms. The same as out_ms
