Hey Pat, looks like you (sort of) already have a latlong map... it just
needs to be 2:1 aspect ratio to map onto the sphere properly. Try
reformatting. -E
set cut_paste_input [stack 0]
version 6.2 v4
push $cut_paste_input
Reformat {
type "to box"
box_width {{input.width i}}
box_height {{width/2 i}}
box_fixed true
black_outside true
name Reformat3
selected true
xpos 1144
ypos 1223
}
