0 Overview

In the following the Tübingen NLTE Model-Atmosphere Package (TMAP)is described, which is based on the approximated lambda iteration (ALI) method. It consists mainly out of a “LTE” model atmosphere program (LTE2) for the calculation of start models, a NLTE program (PRO2), a NLTE line formation program (LINE1) and a plot program (PROF1). To start the programs you need the following:

1. an executable program of the most recent program version. Details can be found in Sect. 1.
2. a model atom file with all model atoms and atomic data. This file is created by the user and partly checked and automatically filled up by the program ATOMS2 (Sect. 2).
3. a frequency grid file, which contains the frequency points, the respective quadrature weights, and informations about every frequency point. It is created by the program SETF2. Details can be found in Section 3.
4. a start model. It can be either a “LTE” start model or a model which has been created by PRO2 or LINE1. Further informations are summarized in Section 4.
5. commands for the program control (Sect. 5.4) and print commands (Sect. 5.5).
