I have ISIS installed.
I would like to download several new target definition files, such as tethys.def
I tried using rsync and running isis_install, but it will NOT update my data directories without re-installing isis.
I only want to download the NAIF files and target definitions that i do not already have. I do not want to update the software - it works(!)
Is there an FTP or Web site where i can download ONLY the files i want, such as tethys.def, 05058_05099pg_psiv2.bc, iapetus.def.1, cas00091.tsc, m01_ext2.bsp
Failing that, is there a way to modify the isis_install script so it will ONLY download the files i want - and will put them in the directories i already have set up??
