aoquality 0.3.0

Python module to access Measurement Sets' quality statistics produced by aoflagger, aoquality or DPPP.

aoquality

aoquality reads and analyses the Measurement Set quality statistics produced by AOFlagger, aoquality, or DP3.

It provides a small Python API over the three AOQuality table types (baseline, frequency, and time statistics) — reading a single Measurement Set or combining many — and a command-line tool, aostats, for diagnostic plots and outlier detection across many observations.

Documentation: https://pyaoquality.readthedocs.io

Installation

pip install aoquality

Requires Python ≥ 3.8.

Quick start

Python API:

import aoquality

bl = aoquality.BaselineStat('obs.MS')
ant_names, ant_stats = bl.get_antenna_stat('SNR')   # (n_ant,), (n_ant, n_pol)

Command line:

aostats plot obs.MS SNR -o stat_snr            # single-MS diagnostic plots
aostats plot-grid obs1/ obs2/ obs3/ SNR        # multi-observation grids
aostats find-bad-stations *.qs SNR -o bad.json # flag outlier antennas

See the documentation for the full Python API, usage guide, and aostats command-line reference.
