Guide for each driver
=====================

Here we presents the useage of each drivers imported to pymoog in detail.

MOOG provides 14 drivers used for various purpose, and 9 of them are imported in `pymoog`:

There are two more functions which are available in `pymoog`:

- Contribution function: a function indicating where the lines are formed in the atmosphere
- MPFIT: an algorithm for self-consistent multi-parameter fitting for spectra, by `Takeda (1995) <https://ui.adsabs.harvard.edu/abs/1995PASJ...47..287T>`_ .

The following links provide the usage of each driver and function listed above.
