The altimeter was Andrew's Garmin GPS model "vista" #79982554" which includes a built in pressure altimeter with milliBar readout. The data is in the form {"Pressure" [milliBar], "Raw ADC values"} where the raw ADC values are hexadecimal numbers. {"538.5", "78a"}, {"540.0", "790"}, {"541.2", "795"}, {"541.6", "797"}, {"653.1", "988"}, {"653.6", "98a"}, {"654.0", "98b"}, {"654.3", "98d"}, {"750.2", "b38"}, {"750.3", "b39"}, {"750.8", "b3b"}, {"751.3", "b3d"}, {"837.2", "cbb"}, {"837.5", "cbc"}, {"837.7", "cbd"}, {"838.0", "cbf"}, {"431.1", "5aa"}, {"432.0", "5af"}, {"433.5", "5b5"}, {"434.7", "5bb"}, {"330.0", "3e5"}, {"331.0", "3ea"}, {"332.3", "3f0"}, {"334.1", "3f7"}, {"1006.0","fa5.8"}
