# MCALF models¶

This sub-package contains:

• Base and sample models that can be adapted and fitted to any spectral imaging dataset.

• Models optimised for particular data sets that can be used directly.

• Data structures for storing and exporting the fitted parameters, as well as simplifying the calculation of velocities.

## mcalf.models Package¶

### Classes¶

 FitResult(fitted_parameters, fit_info) Class that holds the result of a fit. FitResults(shape, n_parameters[, time]) Class that holds multiple fit results in a way that can be easily processed. IBIS8542Model(*[, constant_wavelengths, …]) Class for working with IBIS 8542 Å calcium II spectral imaging observations. ModelBase(*[, original_wavelengths, …]) Base class for spectral line model fitting.
