In order to facilitate the exchange of stellar models produced by different evolution codes, both for the comparison of the models and for the calculation of their frequencies of oscillation, this simple tool (in FORTRAN) has been created. It will read a model in a specific format in order to produce an output file in a different format.

For a detailed description of the File Formats please see the latest version (2005-11-21) of the CoRoT/ESTA document.

The conversions already available (more will be implemented as necessary) are;

Input format (and code)	Output format(s)
GONG (ASTEC)	FGONG (ASTEC) -- OSC (CESAM) -- AMDL (ADIPLS) -- FAMDL (ADIPLS)
FGONG (ASTEC)	OSC (CESAM) -- AMDL (ADIPLS) -- FAMDL (ADIPLS) -- SROX (OSCROX)
OSC (CESAM)	FGONG (ASTEC) -- AMDL (ADIPLS) -- FAMDL (ADIPLS) -- SROX (STAROX)
SROX (STAROX)	FGONG (ASTEC) -- AMDL (ADIPLS) -- FAMDL (ADIPLS)

If you would like to proposed an additional option as input and/or output format, please send me the details.

MODCONV Version 0.3 (2005-11-21):

This version can be downloaded as a tar-gzip file containing the following files:

• README.txt - text file with a summary of the information provided in this page and a list of the latest changes.
• Makefile - text file with the rules for compiling the ".f" files in order to produce the executable file "convert". This file has to be adapted to the local setup and options of the FORTRAN compiler.
• modconv.f - main programme from which all other subroutines are called. It establishes what conversion is to be done and calls the relevant subroutines.
• ref_data.f - subroutine where the references data (constants and solar values) are defined, as adopted for the ESTA.
• read_gong.f -- read_fgong.f -- read_osc.f -- read_amdl.f -- read_srox.f - subroutines for reading in the data as provided by each format. More subroutines will be made available if necessary to include other input formats.
• write_fgong.f -- write_osc.f -- write_amdl.f -- write_srox.f - subroutines for writing out the data in the required formats. More subroutines will be made available if necessary to include other output formats.

In order to use this tool you will need to compile it by entering "make modconv".

Alternatively, you may also choose to add one of the "read_???.f" subroutines to existing programmes in order to hardwire the reading option into your code.

WARNING: This is not a fully functional version of all subroutines, it has not been fully tested, and some of the conversions do not produce full conversions (some items are not included in the output). Please use with caution and let me know of any serious (and no-so-serious) errors you may find, as well as of any addition that should be implemented. Any suggestions and/or error reports are very much appreciated.
