the coefficients).

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.

Print a string representation of the contents of this mapping, for debugging.
This string representation can be very verbose, as it contains all of the parameters of all of the transforms in this mapping.

Set whether to fit chips or visits.
This must be called before anything that depends on knowing the number of parameters in the fit, such as offsetParams(), getParameters(), or computeParameterDerivatives().
fittingChips | Fit the chip transform. |
fittingVisits | Fit the visit transform. |
