Handle AOFlagger measurement set quality statistics

## NAME

AOQuality - Handle AOFlagger measurement set quality statistics

## SYNOPSIS

**aoquality** \<action\> \[*options*\]

## ACTIONS

- **help**

  Get more info about an action (usage: 'aoquality help \<action\>')

- **collect** \[-c/-tf/-h\] \<ms\> \[quack timesteps\] \[list of antennae\]

  The collect action will go over a whole measurement set and  collect the default statistics. It will write the results in the  quality subtables of the main measurement set.

-

  Currently, the default statistics are: RFIRatio, Count, Mean, SumP2, DCount, DMean, DSumP2.

-

  The subtables that will be updated are: QUALITY\_KIND\_NAME, QUALITY\_TIME\_STATISTIC, QUALITY\_FREQUENCY\_STATISTIC and QUALITY\_BASELINE\_STATISTIC.

-

  **-c** will use the CORRECTED\_DATA column. and writes them in the quality tables.

- **combine** \<target\_ms\> \[\<in\_ms\> \[\<in\_ms\> ..\]

  This will read all given input measurement sets, combine the statistics and  write the results to a target measurement set. The target measurement set should not exist beforehand.

- **histogram** \<query\> \<ms\>

  Various histogram actions.

-

  Query can be: rfislope - performs linear regression on the part of the histogram that should contain the RFI. Reports one value per polarisation.

- **liststats**

  Display a list of possible statistic kinds.

- **query\_b** \<kind\> \<ms\>

  Prints the given statistic for each baseline.

- **query\_t** \<kind\> \<ms\>

  Print the given statistic for each time step.

- **query\_f** \<kind\> \<ms\>

  Print the given statistic for each frequency.

- **query\_g** \<kind\> \<ms\>

  Print the given statistic for this measurement set.

- **remove** \[ms\]

  Completely remove all quality tables from the measurement set.

- **summarize** \<ms\>

  Gives a summary of the statistics in the measurement set.

- **summarizerfi**

  Give a summary of the rfi statistics.

A few actions take a statistic kind. Some common statistic kinds are: StandardDeviation, Variance, Mean, RFIPercentage, RFIRatio, Count. These are case sensitive. Run 'aoquality liststats' for a full list.
