As we're setting up we'll put in the numbers we're recording...
Note St9 is slightly different because we didn't notice until later that the compass had a previous non-zero deviation cranked in, which we subsequently removed and took the 'correct reading'. ie. all compass readings are with respect to a '0-degree' deviation angle.
Note: Sonic angles are looking into the boom. ie the sensors are pointing to the northeast roughly toward the wind generator.
Note: Gill angles are looking from the boom to the SE. The red dot is oriented pointed toward the boom, ie 180+reading.
CHECK/EDIT: Note Comms (8/19): It's possible that cell coverage is more spotty on the west side of the network and links may not be as good. At one point we thought Vipers had a unique problem connecting but on 8/19, site 2 came up just fine, whereas sites on the west have had significantly more drops.
Readings by Steve&Andy starting 9/23 using the binoculars.

| 4 | 8/18 | T | 672 | 3.16 | 226 227 | 1536007 | 320 136 | - | no Pmon cable. |

| 6 | 8/23 | T | 673 | 3.15 | 226 225 | 1336044 | 318 139 137 | - | The PV stand got marsh water on it above the 'top' connector panel; sprayed/lubed but watch this maybe |
| 7 | 8/23 | V | 800 | 3.138 | 223 221 | 1335016 | 136 136 | - | Viper bootup speed system services issues here. /media/usbdisk mounted but there data recording did start until we remove/re-installed the disk when the dsm was up. Ditto for the usb cell modem |
| 8 | 8/22 | T | 540 | 3.11 | 225 222 222 | 1335017 | 131 135 128 127 | - | Blue values were measured on 10/12 (tripod may have been the issue, had some affect on the compass reading) |
| 9 | 8/15 | T | 853 | 3.13 | 210 210 | 1536009 | 120 118 | - | |

| 11 | 8/16 | V | 855 | 3.16 | 220 221 | 1536010 | 130 133 | - | Cell modem was started up by Gary's technique of unplugging and replugging it in and then the cdc_ether services / eth1 came up and established cell connectivity. |
| 12 | 8/17 | T | 537 | 3.135 | 228 226 224 | 1536008 | 141 136 131 | - | No PwrMon cable. 8/23: Gill 2D was bad because of the bad cable. Swapped it and put the sensor back on port 4 after presumably DrO. reassigned it to 6. ie locally edited vertes.xml back to '4' |
| 13 | 8/16 | T | 1117 | 3.20 | 231 | 1536012 | 139 | - | PwrMon has the old style 3AG fuse. Using 20 or 25A Green values shot Oct 11, after replacing 3D sonic with EC150. 2D Gill shot from the East. |
| 14 | 8/18 | V | 677 | 3.155 | 221 219 | 1536005 | 131 132 | - | Very wet. Access via john boat up small canal +/-2 hours from high tide. Last ditch on walk-in side of canal can't be crossed near high tide; low tide only walk-in. See 'cell modem' note from 8, similar situation |
| 15 | 8/24 | T | 1312 | 3.10 | 225 225 225 | 1536013 | 313 136 129 131 | B4 | Has 3 Radiometers and leaf wetness but no soil sensors yet since the marsh appears to be getting swept with a few inches of water every high tide. |

Note that the Gill boom angles for stations 4,6 and 15 are about 180 different than the others. When I used those values in processing the winds from those stations differed by about 180 from the Gills, and also from the 3d sonic wind directions.
So apparently the Gills on 4, 6 and 15 are not mounted 180 different than the others, and one should subtract 180 from the stated values.
