Flagged data summary

Table: uid___A002_Xeea188_X1f88.ms.h_tsyscal.s6_1.tsyscal.tbl

Summary of flagged solutions. Each cell states the amount of solutions flagged as a fraction of the specified data selection, with the Flagging Step columns giving this information per flagging step. Note: for each data selection intent, the flagging statistics are calculated for the Tsys scans (with intent=ATMOSPHERE) that cover those fields that also match the data selection intent. A value of "N/A" in a row means that no Tsys scan was acquired on the object(s) observed for the corresponding intent.

Flag Step Details

The following section provides plots showing the flagging metrics that the pipeline uses to determine deviant Tsys measurements, and the flagging commands that resulted from each flagging metric. For certain flagging metrics, the pipeline evaluates the metric separately for each polarisation. However, if the Tsys measurement for an antenna is found to be deviant in one polarisation, the pipeline will flag the antenna for both polarisations.
