In order to subtract the limb darkening from H
or white light pictures you can call:
IDL> img_out = rm_darklimb(Haimage)
where Haimage is the name of the H image with limb darkening and img_out is the new H image with limb darkening removed. RM_DARKLIMB does not work if the image is oblate. The image should then be viewed with TVSCL (not TV).
