This file contains 4 axial sections of each time slice 3 thru 13. File names are coded as follows: Using the example file name "exx-s03-m26.csv" exx is the ex field component sliced perpendicular to the x axis. And so forth. s03 is the third time slice of the h5 file containing the ex component. m26 is 26 rows in the minus direction from the center row of the h5 file, corresponding to likely row 123 - 26 or row 98 of the corresponding exy, exz csv files. But check because it could be 123 - (-26) or row 149 of the corresponding csv files. In the example file name, "exx-s03-p26.csv" exx and s03 are the same as above. p26 is 26 rows in the plus direction from the center row of the h5 file, likely corresponding to row 123 + 26 or row 149, but check, because it could be row 123 + (-26) or row 98. There are slices across the x axis at -85, -26, +26 and +85 from the zero center (row 123) of the corresponding ey and ez files. That is, rows 39, 98, 150 and 209 as counted from the top and corresponding to those row counts in the EM cavity, counted either from the top, or the bottom. The reason I'm confused about this is that at the moment, I can't tell which end is up. :(
