SuperK X-Ray Test Images

What's the data file about? From Andy's message:

Below is a list of X, Y, and Z coordinates, in meters, which represent my best estimate of where the mountain surface is, in "SuperK" coordinates. SuperK coordinates, quite naturally, have the SuperK experiment located at (0,0,0). North is said to be (we are not sure whether it is magnetic or true North) at 227.5 degrees in SuperK coordinates, almost exactly halfway between the negative X and negative Y directions. The accuracy of the points is not so reliable at angles very near the horizon. Even though the X and Y data may range from -4000 to +4000 meters, there is a lot of uncertainty in these far outlying points, so if the map looks strange to you out at the edges for any reason, I wouldn't worry about it.

2-D color maps

Click here for full picture. Here, the Matlab function fill() did all the work (see also the short source code). The colors are representing the Z data (height/altitude above the SuperK tank), with green and yellow areas = lower altitudes (approx. 100-200 m), brown areas = middle altitudes (approx. 300-600 m), grey and white = higher altitudes (approx. 800-1000 m), and blue-ish = highest (above 1000 m), with a red * marking the peak. The X and Y axis in this picture refer to the orignal X and Y components in the data file. North is at 227.5 degrees with these coordinates.
