6. Displays now available
Omitting lines illustrating chamber surface
Triangles show the slope well enough
PG information not displayed
Diagram is very cluttered already
HSLM1-5 are animated to show 0 to 3.8T shifts
HSLM6 has bad data for the DCOPS at 3.8T and bad Z information for the distancemeter
HSLM3 probably has bad distancemeter data also
