Detailed Description

The Schedule class represents a planned rotation of the telescope.

This can be either a slew from one position directly to another (which will typically happen by a great-circle route) or it will generate the rotations to track an object across the celestial sphere (typically along a small circle).

Member Function Documentation

double Schedule::phidot ( void  ) const

inline

Obtain the suggested azimuthal angular speed.

The speed is positive for clockwise rotations about the zenith.

Returns

angular speed; units of rad/s.

virtual ms_t Schedule::step ( double  current_phi, double  current_theta, ms_t  t  )

pure virtual

Update the schedule with the current position of the system.

Step the schedule to the given time

Parameters

current_phi	the current pointing of the system (azimuth, rad)
current_theta	the current pointing of the system (altitude, rad)
t	the current time

Returns

a new suggested step time, or zero to indicate that we've arrived at a destination, or should otherwise stop

Implemented in TrackingSchedule, and SlewSchedule.

double Schedule::thetadot ( void  ) const

inline

Obtain the suggested altitudinal angular speed.

The speed is positive for rotations towards the zenith.

Returns

angular speed; units of rad/s.

Member Data Documentation

double Schedule::thetadot_

protected

Suggested rate of change of theta (altitude coordinate, rad/s).

Thus this is positive for rotations towards from the zenith.
