Detailed Description
DPPP step class to flag using aoflagger's functionality.
This class is a Step class flagging data points based on the aoflagger library written by Andre Offringa. See the following papers for background information:
- Post-correlation radio frequency interference classification methods – http://arxiv.org/abs/1002.1957
- A LOFAR RFI detection pipeline and its first results – http://arxiv.org/abs/1007.2089
When a correlation is flagged, all correlations for that data point are flagged. It is possible to specify which correlations have to be taken into account when flagging. Using, say, only XX may boost performance with a factor 4, but miss points to be flagged. It is also possible to specify the order in which the correlations have to be tested.
It is possible to flag specific baselines only using a selection on baseline length.
Furthermore it is possible to only flag the autocorrelations and apply the resulting flags to the crosscorrelations, possibly selected on baseline length.
Constructor & Destructor Documentation
◆ AOFlaggerStep()
| dp3::steps::AOFlaggerStep::AOFlaggerStep | ( | const common::ParameterSet & | , |
| const std::string & | prefix | ||
| ) |
Construct the object. Parameters are obtained from the parset using the given prefix.
◆ ~AOFlaggerStep()

Member Function Documentation
◆ addToMS()
|
overridevirtual |
Write the statistics into the MS.
Reimplemented from dp3::steps::Step.
◆ finish()
|
overridevirtual |
Finish the processing of this step and subsequent steps.
Implements dp3::steps::Step.
◆ getProvidedFields()
|
inlineoverridevirtual |
Get the fields provided (modified and/or created) by the current step. The returned fields thus should not include (required) fields that are forwarded without modifications.
Implements dp3::steps::Step.
◆ getRequiredFields()
|
inlineoverridevirtual |
Get the fields required by the current step.
Implements dp3::steps::Step.
◆ process()
|
overridevirtual |
Process the data. When processed, it invokes the process function of the next step.
Reimplemented from dp3::steps::Step.
◆ show()
|
overridevirtual |
Show the step parameters.
Implements dp3::steps::Step.
◆ showCounts()
|
overridevirtual |
Show the flagger counts.
Reimplemented from dp3::steps::Step.
◆ showTimings()
|
overridevirtual |
Show the timings.
Reimplemented from dp3::steps::Step.
◆ updateInfo()
|
overridevirtual |
Update the general info. It is used to adjust the parms if needed.
Reimplemented from dp3::steps::Step.
