The ProSpecTIR VS system was flown by SpecTIR, LLC. The system is a hyperspectral pushbroom spectrometer with 356 bands, coving the 400 - 240 nm range. The sensor looked from nadir, and had a 24 degree field of view. It flew all sites, and covered the Avon ground truth site in both the morning and afternoon. The flight altitude and gain varied only over the Conesus lake site; the altitude was lowered and the gain increased to increase the image fidelity over water. The quantization of this system varies according to the spectral range, with the VNIR having quantization of 12 bits and the SWIR having quantization of 14 bits.
