Sorry I will try again!

Hi all

I would like to convolve a spectrum (output from MODTRAN) with a
spectral response curve (Landsat7 B62) and then integrate the
convoluted result. As you can see from the example below the spectral
resolution does not match.

Eg. Spectrum:

Wavenumber Radiance
800.0 7.52E-004
801.0 7.66E-004
802.0 7.58E-004
803.0 7.25E-004
804.0 7.23E-004
805.0 7.62E-004

Eg. Response

Wavenuber Relative Spectral response
800.00000 0.2
800.64051 0.29
801.28205 0.27
801.92462 0.28
802.56822 0.36
803.21285 0.36
803.85852 0.39
804.50523 0.41
805.15298 0.42
805.80177 0.43
806.45161 0.45

Any help would be much appreciated.
