Compute the derivatives with respect to the parameters (i.e.
the coefficients).
[in] | x | The x coordinate to compute at (in the appropriate units for this transform). |
[in] | y | The y coordinate to compute at (in the appropriate units for this 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. |
Implemented in lsst::jointcal::MagnitudeTransformChebyshev, lsst::jointcal::FluxTransformChebyshev, lsst::jointcal::MagnitudeTransformSpatiallyInvariant, and lsst::jointcal::FluxTransformSpatiallyInvariant.
