1. First, a question about the sense of EOF's:

 * 1) How many values (numbers) are in your input data array? 144 x 240
 * 2) How many values (numbers) are needed to build each term on the left? 144 for EOFs, 240 for PCs
 * 3) If 5 EOFs capture most of the data's variance, how much smaller (in the above sense) is the EOFxPC representation compared to the full data set? 144x240 - 5x240
