OYSTER

Conditions for the use of OYSTER

The software is provided to you for academic and/or non-profit research purposes only, without fees. It is provided on an "as is" basis without any obligations on the author's part to maintain, support, update, enhance, or modify it. The software comes without warranty of any kind, and the author is not responsible for any adverse consequences resulting from its use. No assurance of suitability for any purpose is implied by its availability for copying.

Three main C code subroutine libraries used by OYSTER and included in this distribution (but see note below) in their original form are the intellectual property of others. These are the Naval Observatory Vector Astrometry Subroutines (NOVAS), the Hierarchical Data System by STARLINK (HDS), and the Flexible Image Transport System I/O package by the High Energy Astrophysics Science Archive Research Center (FITSIO).

The OYSTER IDL code library also contains the IDLASTRO IDL astronomy library, and the OI-DATA IDL Utilities written by J. Monnier.

Downloading OYSTER

The complete OYSTER installation is contained in the three files below.

Oyster (public 32/64 bit version 7.06, released October 15, 2009)
Catalogs (revised for version 7.05)
Atmospheres (revised for version 4.00)

The IDL script code is regularly updated and can be downloaded with the link below in order to upgrade to the most recent version. Place the file in the main OYSTER directory and unpack it there using "tar zxvf update.tar.gz ". Then change to directory "source/itt" and run the command "idl c". This will also update a few miscellaneous other files, most notably the Earth rotation database. This update does not include updates to the C code library. Whenever the C code library changes, a new version is released.

Updates (version 6.15, June 2, 2008)

First time installation from downloads

Unpack (tar zxvf) the OYSTER archive first, this will create a folder named oyster in your current directory. Then save the other two archive files to the same folder and unpack them there. This will create folders atmospheres and catalogs.
Check your system using the uname command. It must be one of the following: Linux, SunOS, HP-UX, or Darwin.
Edit the file Makefile.Linux.in in the source/itt folder (if Linux is your OS, for example) to enter the path of the IDL main directory (e.g. itt/idl71) for the IDL variable.
Then run make in the main OYSTER directory. This will compile all C code, as well as the script libraries. It will also create a startup file for your system, oyster.pro, located in the main directory.
To start OYSTER, just type idl oyster.pro (including the full path if necessary). Then, if this is a first time installation, you need to run these two commands to create necessary files in the atmospheres folder since these are not in the downloaded distribution:
```
limbdata
```
and
```
kurudata,'ip00k2.pck19'
```
(The second one could be skipped if you are not planning to model data using the Kurucz atmospheres.)

For further information, please refer to the manual (oyster.ps) in the document directory (oyster/docs).
