Value transform takes ownership of transfo, error transform aliases it.
Call freezeErrorTransform() to unalias the error transform.

Compute the derivatives with respect to the parameters (i.e.
the coefficients).
[in] | measuredStar | The measured star position to transform. |
[in] | value | The instrument flux or magnitude to compute the derivative at. |
[out] | derivatives | The computed derivatives, in the same order as the deltas in offsetParams. |

Once this routine has been called, the error transform is not modified by offsetParams().
The routine can be called when the mappings are roughly in place. After the call, the transformations used to propagate errors are no longer affected when updating the mappings. This allows an exactly linear fit, which can be necessary for some model+data combinations.
