Hello John
pun19 and pun08 were collected at the beginning of june.
pun12 was at the end of june.
lau, sta07, sta08, sta09, sta11 were acquired simultaneously at the beginning of March.  You can see by the file size, where the data card swap was done (at the end of file 2 before file 3).  
these files have all 6 channels.  The used channels are typically 1,2, 4,5 (Hx, Hy, ex and ey) unless there was a bad channel.  Lau has a second (parallel) Hy coil.  In some cases the coil may have a reverse polarity, likewise the orientation of E fields has not been corrected...In most cases we orient x at 135 and y at 225.  At Lau Ex is oriented at 315.
