Hi, I'm reporting here my efforts in contacting iraf developers. First I sent a message to admin at iraf.net the "contact us" addres in iraf.net. As I haven't received any answer back, I have posted the message in the iraf.net forums[1]. Let's see if something happens. Regards, Sergio [1] http://iraf.net/phpBB2/viewtopic.php?p=139694
