SVConverter
A container for the conversion from spherical coordinates to
6-Vectors.
You create one with an example of your data; these are values and
units of STC objects, and everything may be None if it's not given.
The resulting object has methods to6 taking values like the one
provided by you and returning a 6-vector, and from6 returning a pair of
such values.
Further, the converter has the attributes distGiven, posdGiven,
and distdGiven signifying whether these items are expected or valid on
return. If posVals is None, no transforms can be computed.
The relativistic=True constructior argument requests that the
transformation be Lorentz-invariant. Do not use that, though, since
there are unsolved numerical issues.
The slaComp=True constructor argument requests that some operations
exterior to the construction are done as slalib does them, rather than
alternative approaches.

|
returns a function that transforms 2- or 3-spherical coordinates using
the 6-vector transformation sixTrafo.
Regardless of whether we expect distances, the returned function
always returns vectors of the same dimensionality as were passed in.
This is used when transforming areas.
|
getVelocityTransformer(self,
sixTrafo,
basePos)
| source code
|
returns a function that transforms velocities using sixTrafos at
basePos.
This is used when tranforming velocity intervals.
