I do not know how these datasets were generated, so I don't know what format (big/little endian, byte swapped, etc) they are in.

A few minutes of LabVIEW work shows some semi-reasonable values if you swap bytes:
BF49E37D5372053C = -0.000790058
C0A8E32F5B13094F = -3185.59
Do you know that those values are wrong?
