Simulated One Point Mode

This mode is currently only supported for Mars.

It requires to provide: 1: a Temperature T 2: @ a season ls 3: @ a LTST hour 

 OUT = krc(lat = 0., lon = 0., T = 170., ls = 152.4, hour = 3.12)

The output is the equivalent thermal inertia in J m-2 K-1 s-1/2, in this case OUT = XXX.

The One-Point Mode outputs a TI (SI) for an array of input temperatures with the given parameters

It can output various values that indicate why a TI was not derived for failure cases:

-600: The Temperature provided is lower than the lowest model output. Possible Frost Presence
-500: No value was derived or returned. KRC may have failed to run all together
-400: Negative TI value. This is a non-physical return as a function of the fitting routine
-300: TI value larger than 2200 SI. 2200 SI is the top of the available lookup table and extrapolation is not permitted
-200: Returned TI value doesn't meet proximity criterion (TI_Guess_PCT)
-100: Bad TI_Guess / TI_Guess_PCT combination. This is most likely a user error


SOMETHING ABOUT TI_Guess_PCT and TI_Guess

Validity not met => -200. 

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=300.,TI_Guess_PCT=0.05)


Validity met => 334. 

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=300.,TI_Guess_PCT=0.2)

No validity criterion specified, good guess => 334. 

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=300.)

No validity criterion specified, poor guess => 641. You shoot yourself in the foot 

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=900.)

No guess, slow, => 334.   

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.)

Pathological Case; KRC runs, sets TI_Guess to 0., and returns a flag => -100. 

OUT = krc(T=190,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess_PCT=0.2)

Below Frost point => -600. (The solution was a negative TI) 

OUT = krc(T=130,ls=0.,hour=4.,lat=12.,lon=12.)

Below Frost point, horrible guess but -600 

OUT = krc(T=130,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.) 

Below Frost point, horrible guess -200     

OUT = krc(T=130,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.,TI_Guess_PCT=0.5)

     Much too warm => flags high TI => -300.                                                            

OUT = krc(T=500,ls=0.,hour=4.,lat=12.,lon=12.)

Much too warm, poor guess => flags high TI => -300. 

OUT = krc(T=500,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.)

OUT = krc(T=500,ls=0.,hour=4.,lat=12.,lon=12.,TI_Guess=200.,TI_Guess_PCT=0.1)             #Much too warm, poor guess => flags poor guess => -200.



OUT = krc(T=190,ls=000.00,hour=4.,lat=12.,lon=12.)                                        #No guess, slow, => 334.



OUT = krc(T=190,ls=359.99,hour=4.,lat=12.,lon=12.)                                        #No guess, slow, => 334.



OUT = krc(T=190,ls=359.99,hour=4.,lat=12.,lon=12.,DELLS=0.)                                 #sets DELLS=0. to avoid this issue but error message: Please do not set both DELLS and DELJUL XXX
