Function Documentation

void tcc::tcspk::pvtFromTCS	(	coordConv::PVT &	pvt,
		double	posArr[2],
		double	tai,
		double	deltaTAI,
		bool	isAz = false
	)

Compute a PVT given a pair of angles (in rad)

Parameters

[out]	pvt	the pvt to be set
[in]	posArr:	a pair of angles (rad): computed at tai and tai + DeltaTForVel
[in]	tai:	TAI date of posArr[0] (MJD seconds)
[in]	deltaTAI:	time of posArr[1] = tai + deltaTAI
[in]	isAz:	the angle is azimuth; switch conventions (TCC is S to E, TCSpk is N to E)

double tcc::tcspk::rotPhysFromTcs ( double  rotTcs, tcc::InstPosition const &  instPos  )

inline

Convert rotator angle from Tcs mechanical (radians) to TCC physical (degrees)

Definition at line 92 of file tcsShim.h.

double tcc::tcspk::rotTcsFromPhys ( double  rotPhys, tcc::InstPosition const &  instPos  )

inline

Convert rotator angle from TCC physical (degrees) to Tcs mechanical (radians)

Definition at line 85 of file tcsShim.h.

bool tcc::tcspk::tcsFromPVT	(	double &	pos,
		double &	vel,
		coordConv::PVT const &	pvt,
		double	tai,
		bool	isAz = false
	)

Convert a TCC PVT into tcs units; if the PVT is invalid then use 0, 0

This is a best-effort approach intended to feed the command and achieved inputs for mount position to TCSSpk.

Parameters

[out]	pos	position in rad
[out]	vel	velocity in rad/day
[in]	pvt:	PVT to convert
[in]	tai:	TAI at which to compute position (MJD, seconds)
[in]	isAz:	the angle is azimuth; switch conventions (TCC is S to E, TCSpk is N to E)

Returns

isfinite: true if pvt is finite
