Name: PortableHi-Resolution:LDEO

Sample Interval (msec): 0.5

Details

Record Length: 3.0 seconds for line 6

Record Length: 2.8 seconds for lines 8,10

Record Length: 2.6 seconds for lines 12,14,16,22,1,24,26,28,32,34,30,33,31.1

Shot Interval: 3 seconds for about 6.25 meters

ACQ001 and ACQ002

Number of Channels: Channels 1-48 were recorded, channels 1-5 were not usable

Source to Near Channel: Channel 6 (the near channel) and the source were both 52 meters from the antenna with a lateral distance between them of ~5.5 meters. Recorded channels 25-48 were actually channels 48-25 so either they must be renumbered or the offsets calculated accordingly.
