Project description
msv4-utils
Lightweight utilities for reasoning about Measurement Set v4. Core functionality depends only on the Python standard library.
Installation
pip install msv4-utils
Usage
Infer the MSv4 backend from a URI
from msv4_utils import infer_backend, MSv4Backend
backend = infer_backend("/path/to/data.ms")
if backend == MSv4Backend.CASA_TABLE:
# open with xarray-ms
...
elif backend == MSv4Backend.ZARR:
# open with xarray
...
elif backend == MSv4Backend.MEERKAT:
# open with xarray-kat
...
MSv4 type constants
from msv4_utils.msv4_types import VISIBILITY_XDS_TYPES
xds_type = xds.attrs["type"]
if xds_type in VISIBILITY_XDS_TYPES:
print("interferometric data")
