All the block have been measured (in some cases remeasured) such that the Mz component is also measured.  
For all of the blocks the first run (.ru1) is a measurement of Mx and My (this is an arbitrary designation since there is no markings on the blocks) and then the block was rotated counter clockwise 90 degrees around the x axis and remeasured making run 2 a measurement of Mx and Mz.   
There is also a summary file though it doesn’t list the second run values as being Mx and Mz, instead we will have to rely on the file description to remember the measurement setup.
