Compute a slew to a given user-specified position, by iteration.
Before calling this:
This routine then does the following for each axis:
[in,out] | obj | object block: input: object block computed at approximately the current time (see above) output:
|
[in] | minEndTime | earliest date at which slew may finish (TAI, MJD sec) |
[in] | earth | earth orientation data, a tcc.base.Earth |
[in] | inst | instrument-position information block, a tcc.base.Inst |
[in] | telMod | telescope model, a tcc.base.TelMod |
[in] | axeLim | axes limits block, a tcc.base.AxeLim |
[in] | tune | axes motion tuning constants block, a tc.base.Tune |
RuntimeError | if any of the following are true:
|
Special cases:
Details: The slew path is computed by iteration, as follows:
There are several parameters in the Tune block which control this iteration process. See TuneBlkDef for more info.
