Detailed Description

Instrumental passband (or bandpass)

This Extension stores the instrumental bandpass in a Pulsar::Archive.

Member Data Documentation

nband

unsigned Pulsar::Passband::nband

protected

Number of frequency bands.

The number of frequency bands may be other than one when an Archive contains data from multiple bands.

Referenced by operator=(), and Passband().

npol

unsigned Pulsar::Passband::npol

protected

Number of polarizations.

A full polarimetric representation of the bandpass may be stored.

Referenced by operator=(), and Passband().

passband

std::vector< std::vector<float> > Pulsar::Passband::passband

protected

Average passbands.

The passbands are organized in ipol major order, I think. band0,pol0 band0,pol2 ... bandN,polM band1,pol0 ...

Referenced by operator=().
