Member Function Documentation

◆ add_extension()

void Pulsar::Archive::add_extension ( Extension * ext )

virtual

This method ensures that only one instance of the Extension type is stored in the Archive.

Derived classes need only define this method, as the non-const version implemented by the Archive base class simply calls this method.

◆ create_updated_model()

void Pulsar::Archive::create_updated_model ( bool clear_model )

protected

Creates polynomials to span the Integration set.

The polyco need only describe the phase and period of every Integration. When the Integrations are separated by a large amount of time, the creation of a new polyco to completely span this time results in a huge polyco.dat and a huge waste of time.

Therefore, this method attempts to create the minimum set of polyco polynomials required to describe the data. If a match is not found in the current model, a single polynomial is created and appended to the current model.

Parameters

clear_model delete the current model after copying its attributes
