The Pathfinder IMP spectral library is convolved from the splib04b interpolated library for each state of the instrument we have worked with.

Pathfinder IMP filters filters are sprted into increasing wavelength order. All bandpasses were multiplied by the Solar flux and normalized during convolution.

Wavelength Centers at -20C for Pathfinder IMP arranged in increasing wavelength order.
