To diagnose our strange p' spectra problem, I've made 2 changes:
6b - the + side is now plumbed through the CHATS garden hose to the Bedard quad-disk-probe, which I've lashed to the top of the tripod in the middle pitchfork position. Good winds at this location are bit restricted due to the config#3 towers that Steve has erected, but should give us some idea. Changes done 0915-0930.
6t - I've removed this transducer and placed it inside my CHATS sensor tube which is now in buried in the ground near the middle of the horizontal array and covered with a space blanket. The + side is connected to the AHATS reference system and the - side is connected to the reference volume inside this tube. Changes done 0940-1020. Note that the AHATS reference system was open to the world a couple of times during this work.
NOTE THAT THIS DESTROYS THE AHATS p' ARRAY, since no center sensor at either height. I think these tests are worth it, though.
