Public Attributes
ms_t	prog_ref_time_ms
	The prog_ref_time_ms and prog_ref_time_ut objects represent the same time, and tie the two timescales together. More...
AstroTime	prog_ref_time_ut
double	obs_lat
	The actual latitude of the observatory, in radians north.
double	obs_lon
	The actual longitude of the observatory, in radians EAST of Greenwich.
double	max_drive_az
	The maximum azimuthal speed in rad/sec, corresponding to giving the argument 1.0 to the driving function. More...
double	max_drive_alt
	The maximum elevation speed. More...
double	tel_lat_eff
	In contrast to obs_lat and obs_lon, tel_{lat,lon}_eff represent the effective lat/long of the telescope, including corrections for misalignments.
double	tel_lon_eff
double	home_position_phi
	The longitude of the telescope when it is in the home position, in 'polar' radians (ie, east of south, in [-pi,pi]). More...
double	home_position_theta
	The altitude of the telescope when it is in the home position, in radians north of horizontal.
double	antihome_position_phi
	The longitude (as 'polar' radians, east of south) of the telescope when it is in the westmost 'antihome' position. More...

Detailed Description

This struct holds a mixture of environmental and calibration information.

Member Data Documentation

double EnvironmentInformation::antihome_position_phi

The longitude (as 'polar' radians, east of south) of the telescope when it is in the westmost 'antihome' position.

This is in the range [-PI,PI].

double EnvironmentInformation::home_position_phi

The longitude of the telescope when it is in the home position, in 'polar' radians (ie, east of south, in [-pi,pi]).

This must be the eastmost position that the telescope can move to.

double EnvironmentInformation::max_drive_alt

The maximum elevation speed.

See max_drive_az.

double EnvironmentInformation::max_drive_az

The maximum azimuthal speed in rad/sec, corresponding to giving the argument 1.0 to the driving function.

This is useful only for starting the State object from scratch, and the values here will be quickly improved by the Kalman filter within that State object.

ms_t EnvironmentInformation::prog_ref_time_ms

The prog_ref_time_ms and prog_ref_time_ut objects represent the same time, and tie the two timescales together.
