def tcc.axis.oneSlewIter.oneSlewIter	(		doAxis,
			oldMount,
			newMount,
			begTime,
			minTime,
			axeLim
	)

Compute a slew for all axes, given the starting and target paths.

Parameters

[in]	doAxis	slew this axis? A sequence of NAxes bools
[in]	oldMount	initial position, as a list of NAxes PVTs
[in]	newMount	target coordinates, as a list of NAxes PVTs
[in]	begTime	start time (TAI, MJD sec)
[in]	minTime	minimum slew duration (sec)
[in]	axeLim	axes limits, as an tcc.base.AxeLim where NAxes = tcc.base.NAxes

Returns

two items:

• pathList: a list of NAxes pvtLists, where each pvtList is a list of PVTs describing the motion of that axis; if doAxis[axis] is false then pathList[axis] is an empty list
• endTime: end time of slew (TAI, MJD sec)

Exceptions

RuntimeError

if the slew ends too soon or cannot be computed

If no axes are to be slewed (slew not requested, or beginning or ending position is unknown), then endTime = begTime + minTime. No warning is given.
