orca.transform.integrate

Measurement set integration transforms.

Provides functions to combine multiple measurement sets into a single integrated measurement set with a common phase center. Used for creating multi-scan or multi-snapshot datasets for imaging.

Functions

integrate(→ str)

Integrate a list of ms (assumed to be time sorted)

orca.transform.integrate.log[source]
orca.transform.integrate.integrate(ms_list: List[str], out_ms: str, phase_center: astropy.coordinates.SkyCoord | None = None, use_virtualconcat: bool = False) → str[source]

Integrate a list of ms (assumed to be time sorted) chgcentre, concat, and then changing the field id. Common phase center is defaulted to the phase center of the first scan in the list.

Parameters:

  • ms_list – List of (time-sorted) measurement sets to integrate.

  • out_ms – output measurement set path.

  • phase_center – Phase center for the integrated ms.

  • use_virtualconcat – Whether to use virtualconcat, which MOVES the data to create a multi-ms. The original data file will not stay there.

Returns: Path to integrated measurement set.
