class ska_pst_lmc.stat.stat_model.StatMonitorDataStore[source]

A data store for STAT scalar subband monitoring data.

This data store will aggregate the separate data. For now this only handles 1 subband as needed for AA0.5 but for later array assembly releases this needs to aggregate the the separate subband data.

Initialise data store.

property monitor_data: StatMonitorData

Return the current calculated monitoring data.

This aggregates all the individual subband data values into one StatMonitorData instance.

Currently this only supports 1 subband but in the future this will should support multiple subbands. This can be done by knowing the number of samples per statistic from each subband, including the total number and the number that has not been flagged as RFI. For more information about how this can be achieved refer to Wikipedia - Algorithms for calculating variance - Parallel algorithm

Returns

current monitoring data.
