operator()()

Jones< double > Pulsar::ProjectionCorrection::operator()

(

unsigned

isub

)

const

Return the projection correction for the given sub-integration.

Return the transformation matrix for the given epoch.

The Jones matrix should be inverted to calibrate observations.

required()

bool Pulsar::ProjectionCorrection::required

(

unsigned

isub

)

const

Return true if the given sub-integration requires correction.

Return true if the archive needs to be corrected.

set_archive()

void Pulsar::ProjectionCorrection::set_archive

(

const Archive *

_archive

)

Set the archive for which projection corrections will be computed.

Return true if the archive needs to be corrected.
