gemlog-package: File Conversion for 'Gem Infrasound Logger'

In gemlog: File Conversion for 'Gem Infrasound Logger'

Description

Reads data files from the 'Gem infrasound logger' for analysis and converts to segy format (which is convenient for reading with traditional seismic analysis software). The Gem infrasound logger is a low-cost, lightweight, low-power instrument for recording infrasound in field campaigns; email the maintainer for more information.

Examples

## Not run: 
# define bitweight for 0.5 inch sensor with Rg = 2.2k
sensitivity = 22.014e-6 # 22.014 uV/Pa
Rg = 2.2 # gain-setting resistor value in kilo-ohms
gain = 1 + 49.4/2.2 # amplifier gain
A2D = 0.256/2^15 # volts per count in analog-digital converter
bitweight = A2D / (gain * sensitivity) # conversion from counts to Pa (Pa/count)

# convert files from two Gems (SNs 000 and 001)
Convert('raw/000', bitweight = bitweight)
Convert('raw/001', bitweight = bitweight)

## End(Not run)

## Not run: 
ReadGem(0:1, 'raw/000') # read files raw/000/FILE0000.TXT and raw/000/FILE0001.TXT

## End(Not run)
