Detailed Description

Telescope pointing parameters recorded during the observation.

Member Function Documentation

integrate()

void Pulsar::Pointing::integrate ( const Integration *  subint )

virtual

Integrate information from another Integration.

Calculates the mean of the Pointing attributes.

Reimplemented from Pulsar::Integration::Extension.

References Pulsar::Integration::verbose.

update()

void Pulsar::Pointing::update	(	const Integration *	subint,
		const Archive *	archive
	)

Update information based on the provided Integration and Archive.

Based on the epoch of the Integration, uses slalib to re-calculate the following Pointing attributes: local_sidereal_time, parallactic_angle, telescope_azimuth, and telescope_zenith.
