Thank you Lavanya. But, I do not have the Metadata. What I have is the
raw pixel coordinate, Sub observer Lat long and centre pixel
coordinate of venus disc. I would require something like a
transformation matrix and Im looking for the parameters of the same. I
might have to first fix the North pole through the above mentioned
North pole position angle and North pole distance and then interpolate
to find the Latlong for toher pixels.

Aishwarya.
