Orbital parameters have already been processed for some comets:

19P-Borrelly

22P-Kopff

Churyumov-Gerasimenko

Giacobini-Zinner

Halley

Tempel_1

Tempel_2

Wild_2

For these bodies, directly run KRC using the body's name as follow:

body = "BODY_NAME"

For example:

out = krc(lat=0.,INERTIA=50.,T_user=220.,LKofT="T",body="Wild_2",ls=0.)

For other bodies -not in the list above-, the user needs to generate the rotational matrix. First, run PORB to create a structure that can be ingested to generate the orbital rotation matrix. The following arguments are needed:

e: Eccentricity (Default=0)
a: Semi-Major Axis in AU (Default=1)
i: Inclination of mean orbit to ecliptic in degrees (Default=0)
node: Longitude of the asceding node in degrees (Default=0)
per: Argument of perihelion in degrees (Default=0)
m: Mean Anomaly at epoch in degrees (Default=0)
rot_per: siderial rotation period in hours (Default=23.9345)
polera: Right Ascension of the pole in degrees (Default=0)
merid: Prime meridian at epoch in degrees (Default=0)
poledec: Declination of the pole in degrees (Default=0)
period: Sideral orbital period in Earth days (Default=365.256)
name: Body name (default ="None")


Then run generic_porb() with these arguments, for example:

tmp = generic_porb(e=0,a=1.,i=1.3,node=100.4,peri=293.9,m=79.6,rot_per=200.,polera=273.8,poledec=0.,merid=7.7,period=4332.5,name="IdealJupiterTrojan_like_Comet")


Then run KRC using this new body as the "body":

out = krc(lat=0.,lon=0,INERTIA=20.,ALBEDO=.05,LKofT="F",body=tmp)

This case predict surface temperature for a new body named "IdealJupiterTrojan_like_Comet".
