Convert Coordinates from Flat Image to Panoramic location

I have a scene which i want to load hotspots onto , i have their coordinates for when they are a flat image, but how do i do a conversion to make them be in the same place when in a panoramic view. the pano is a single image if that makes a difference.

thank you in advance

They are the same coordinate system. "Flat" is like a zone of a sphere. Therefore no conversion is necessary.
Best regards,

As you probably know the position in the flat image-pixel wise and not degree-wise you will need this conversion:

ath = (source-pixel-x / source-pixel-imagewidth - 0.5) * image-hfov
atv = (source-pixel-y / source-pixel-imageheight - 0.5) * image-vfov
