Hello!
I'm trying to use a subprogram from the Starlink Project - Lucy in the library KAPPA - that is already installed and compiled. The idea is to be able to call it from my fortran routine.
Something like this:
PROGRAM ex
INTEGER i
REAL in(10),psf(10),out(10)
DO i =1,10
in(i) = rand()...
Hello!
One of my assignments for a discipline named planetary systems was to write a program and a paper about the orbit of Eris.
One of the tasks was to find the orbit's characteristics with only one arbitrary point of position and velocity.
Take a look ;)
My best regards, Iris.
Thank you guys, for the replies. So, let me see if i understood.
Please look at the picture and tell me if I'm right.

This picture represents the vector field with the corresponding basis vectors, so, for what I've understood, the covariant derivative...
Hi there!
I saw this exercise that we have to calculate the covariant derivative of a vector field (in polar coordinates). Most of them equals zero, but two of them are non-zero, sugesting that this vector field is not constant. What i want to understand is the physical meaning of this values...
