aoquality

Allows creating and querying of the quality statistics tables. The most common way of running aoquality is like this:

aoquality collect -d CORRECTED_DATA observation.ms

This will stream through all the visibilities in the measurement set, and calculate their statistics in several dimensions. Run aoquality help to see a full list of command, or run aoquality help collect to get more info about the collect action. Other actions are getting a list of statistics over time, frequency, baseline, or query a global statistic. For example:

aoquality query_f StandardDeviation observation.ms

This will output a list of frequencies and the corresponding standard deviation for that frequency.

badstations

Uses the quality statistics inside the measurement set to determine if there are any antennas/dishes which are statistically outliers, or otherwise suspicious (e.g. zero). Run without parameters to get some help on usage. Run as badstations observation.ms to analyze the given observation, or use badstations -flag observations.ms to analyze the set and flag any antennas that are statistical outlyers.
