MCALF: Multi-Component Atmospheric Line Fitting

Determining accurate velocity measurements from observations of the Sun is vital importance to solar physicists who are studying wave dynamics in atmosphere. Weak chromospheric absorption lines, due dynamic events atmosphere, often consist multiple spectral components. Isolating these components allows for field and quiescent regimes be studied independently. However, isolating such particularly challenging wide variety shapes present same dataset. MCALF provides a novel method infrastructure determine Doppler velocities large Each spectrum fitted with model adapted its specific shape.
