KRC for Comets

Revision as of 22:52, 18 July 2018

List of available Comets

General advice about using KRC on Comets

When using KRC on Europa the best practice is to:

• For KRC Davinci Interface, use "comet" as the bodytype
• For KRC Davinci interface, use quotation marks around the bodytype and body parameter (See Command Line Example Below)
• For additional help see the Comets section of the advanced tutorial
