def tcc.axis.ptCorrFromObs.ptCorrFromObs	(		targObs,
			obj,
			inst,
			taiDate
	)

Compute pointing correction position from observed coordinates.

Parameters

[in]	targObs	position of target in observed coordinates (a coordConv.PVTCoord)
[in]	obj	the object block; the following fields are read: objInstXY obsPos objAzInstAng
[in]	inst	the instrument block; the following fields are read: rot_inst_xy rot_inst_ang
[in]	taiDate	TAI date at which to compute (MJD, sec)

Returns

a tuple:

• targPtCorrXY: position of target in pointing correction coordinates (a tcc.base.ArrayPVT2) (deg) i.e. a position in rotator coordinates where X is the direction of increasing azimuth
• targAzPtCorrAng: angle of direction of increasing azimuth at target in ptCorr coordinates (a coordConv.PVT). Warning: do not use this angle to adjust the direction of your pointing correction; pointing correction should be applied using the orientation at the center of the ptCorr frame.
