-<p>OK now for the nasty bit. Many of the older caves did not have easting & northing in UTM 33T at all, but (probably) in BMN and converting between BMN into UTM requires ellipsoids and bessel functions.. or we can just take a linear approximation, which is what I have done here:<br>
-e.northingUTM = e.northingBMN + 5198919.918<br>
-e.eastingUTM = e.easting + 374854.63<br>
-Such converted eastings and northings are <em>in italics</em> in the table below. As you can see, some were wildly out. Well they were until I swapped teh easting/northings around and dealt with obvious typos.
-<p>These magic numbers simply come from assuming that both BMN and UTM are in metres, and linear over our area, and then taking the avergage of the offsets for 5 locations, the 5 cave entrances at the bottom of this page: 
-<a href="http://localhost:8000/handbook/survey/coord.htm#summary">Olaf's Coordinates</a>.
-<p>This horrible approximation is accruate to ~8m in the northing and ~30m in the easting.
