FINISHING UP

Whatever goes out must come back in. Above is a photograph of the area where the North DAS Array was deployed after most of the equipment had been picked up.

Following the two explosions the rest of the day was spent downloading the recorded data and reprogramming the 28 DASs that were to remain in the field, picking up the Texans, and picking up the DASs that would not be left in the field. Above is YongGang Li downloading data from the DAS's internal disk to an exabyte tape recorder.

Each of the DAS's positions were measured using a portable GPS receiver as their data was downloaded. Of the 49 total DASs 28 were left in the field. They were wrapped in plastic bags to protect them from the weather. 21 of the DASs were powered with solar panels. The other seven each had an extra two batteries connected to them to supply their power for the extra few weeks. Above is a photograph of the DAS (in the plastic), the exabyte recorder (standing up), the GPS receiver (in the foreground), and a handheld computer (on top of the recorder) used to send commands to the DAS.

While the DAS data was downloaded in the field, the Texan data was downloaded back at the hotel. There was a relatively small amount of data to deal with, but with the amount of room available it still took about four hours to cycle all of the Texans through the download process.



Above is a photograph of Rufus Catchings and YongGang Li as we all prepared to leave the area. This was a hard project. A lot of driving, a lot of equipment, plenty of heat, but not a lot of time. However, as is usually the case, a good time was had by all.
