KRC for Asteroids

Revision as of 20:38, 18 July 2018

List of available Asteroids

General advice about using KRC on Asteroids

When using KRC on Asteroids the best practice is to:

• For KRC Davinci Interface, use "minor" 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 Asteroids section of the advanced tutorial

Orbital Information for Common Asteroids

All information is taken from minor.tab

All angles are in degrees. Default inertial reference system is:

• J2000 ecliptic for orbital elements
• J2000 equatorial for spin axis (pole)
• PDS uses 1950 Ecliptic for pole
• Flag to indicate this is PM==1.0
