# Ben Cooper 2015-07-10:
# The BoneDig map did not allign with the Surface / Entrance surveys, suggesting there is a blunder somewhere.
# Andrew had equated 1.40@BoneDig to 1.3@BH_Entrance, etc.  However, looking at BoneDig in isolation, 
# there is clearly a problem with leg 1.40-1.0 
# BoneDig: 	1.40 	1.0 	1.426 	216.27 	-47.84  #1.40 top left of door to locked bone cave.  
# Compare this with the similar leg to the middle of the entrance jamb:-
# BoneEntrance: 5.3	5.5	1.462	228.05	-42.61	#5.5  middle of top of door to locked bone cave
# Also, 1.40 is on the edge of a steel plate so would not have been a good place to take a compass shot from!  
# This all sugggests that BoneDig 1.40-1.0 should have been a reverse shot 1.0-1.40.  I've now reversed this in BoneDig.th
# It also suggests that 1.0@BoneDig is very close to 5.3@SurfaceRift2015, and that this is a better equate than 1.3@BoneDig
# Making these two changes and suddenly the BoneDig and PerforationChoke maps overlap quite nicely!
