Instructions for running CIA at IAC: You have to call the UNIX script /net/penca/iso_iac/cia/cia, which will start IDL and then CIA. Alternatively, you could set an alias in your .cshrc file like the following: alias cia '/net/penca/iso_iac/cia/cia' The current version of CIA is OCT98 if you want to run previous version do instead: alias cia '/net/penca/iso_iac/cia/cia.JUN98' Jose Acosta (October 1998) Any question to: jap@iac.es or fgl@iac.es
