oddly:

curly =[-1.912,-1.852,-1.386,-0.818,-0.343,-0.343,-1.233]
larry =[-1.912,-1.852,-1.386,-0.818,-0.343,-0.343,-1.233]
schemp =[-1.912,-1.852,-1.386,-0.818,-0.343,-0.343,-1.233]
curlyjoe=[-1.912,-1.852,-1.386,-0.818,-0.343,-0.343,-1.233]

curly = curly*!PI/180.
larry *= !PI
larry /= 180.

curlyjoe /= 180.
curlyjoe *= !PI

schemp *= !PI
schemp *= 1./180.

diff=curly-larry
diff2=curly-schemp
diff3=curly-curlyjoe

print,diff
print,diff2
print,diff3
