Detailed Description

RFAUVBinner: flagging via UV binning.

Intended use:

Internal

Prerequisite

RFDataMapper
RFFlagCubeBase
RFCubeLattice

Synopsis

To Do

make UV-distance matrix static, to share between multiple instances
collect population statistics across all channels
3D bins (ampl-UVdist-channel)?
think how to solve "encroaching" problem to achieve a better probability distribution. Perhaps two sets of staggered bins, and for each point use the count of the bigger bin?

virtual void casa::RFAUVBinner::endChunk ( ) [virtual]

Called once finished with a chunk.

Reimplemented from casa::RFAFlagCubeBase.

virtual IterMode casa::RFAUVBinner::endData ( ) [virtual]

Called after a pass is completed successfully (i.e., not stopped by start or iter methods).

Return value: STOP to stop, DATA for another data pass, DRY for another dry pass.

Reimplemented from casa::RFAFlagCubeBase.

virtual IterMode casa::RFAUVBinner::endDry ( ) [virtual]

Called after a dry pass is complete.

Reimplemented from casa::RFAFlagCubeBase.

virtual uInt casa::RFAUVBinner::estimateMemoryUse ( ) [virtual]

This method is called before iterating over a chunk, to inquire the expected memory use.

Should return the max desired memory footprint, in MB. Available physical memory is divided between agents in proportion to their requests.

Reimplemented from casa::RFAFlagCubeBase.

static const RecordInterface& casa::RFAUVBinner::getDefaults ( ) [static]

Reimplemented from casa::RFAFlagCubeBase.

virtual String casa::RFAUVBinner::getDesc ( ) [virtual]

called to obtain a short description of this RFA

Reimplemented from casa::RFAFlagCubeBase.

virtual IterMode casa::RFAUVBinner::iterDry ( uInt ) [virtual]

Iteration method for a dry pass.

Called once per each time slot. Return value: STOP to finish iterating, CONT/DRY to continue, or DATA to cancel the dry pass and request another data pass.

Reimplemented from casa::RFAFlagCubeBase.

virtual IterMode casa::RFAUVBinner::iterRow ( uInt ) [virtual]

iterRow() is called once per each row in the VisBuffer.

Iterating over rows is perhaps preferrable in terms of performance, at least for data iterations.

Reimplemented from casa::RFABase.

virtual IterMode casa::RFAUVBinner::iterTime ( uInt ) [virtual]

Iteration methods for a data pass.

Either or both may be implemented. iterTime() is called once for each new VisBuffer (= new time slot) Return value: STOP to finish iterating, CONT/DATA to continue, or DRY to cancel the data pass and request a dry pass.

Reimplemented from casa::RFAFlagCubeBase.

virtual Bool casa::RFAUVBinner::newChunk ( Int & ) [virtual]

Called before iterating over a chunk.

Returns True if agent will process this chunk, or False if this the agent is unable to process it. (this can happen if, e.g., the requisite correlations are not present). The Int & maxmem argument is the number of MB memory which is still available in the memory pool. The agent class should plan its memory use accordingly, and subtract its expected memory use from maxmem. In effect, the agent "reserves" some amount of memory. This is used by RedFlagger to contain the total memory footprint. Note that only a rough reckoning is sufficient, so only bother estimating the biggest data structures. See implementations in RFADiffBase and RFATimeMedian for good examples. nAgent is the total number of agents.

Reimplemented from casa::RFAFlagCubeBase.

virtual void casa::RFAUVBinner::startData ( bool ) [virtual]

Called before starting a data pass on a chunk.

Reimplemented from casa::RFAFlagCubeBase.

virtual void casa::RFAUVBinner::startDry ( bool ) [virtual]

Called before starting a dry pass on a chunk.

Reimplemented from casa::RFAFlagCubeBase.
