== 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 [http://krc.mars.asu.edu/index.php?title=Advanced_Tutorial#Asteroids Asteroids section of the advanced tutorial]
 
 
== Orbital Information for Common Asteroids ==
 
 
All information is taken from [http://krc.mars.asu.edu/svn/filedetails.php?repname=KRC&path=%2Ftrunk%2Frun%2Fminor.tab 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
