### Instruction:

Extract the cause and effect entities from the following sentence:
For the IRS: A spectral channel is defined after spectral resampling of the measured spectral samples to a discrete spectral positions separated according to the spectral channel interval within the spectral band

### Assistant:

VARIABLE: the measured spectral samples to a discrete spectral positions
NOT_RELEVANT: For the IRS:
CONDITION: separated according to the spectral channel interval within the spectral band
KEYWORD: after
EFFECT_1: A spectral channel is defined
CAUSE_1: spectral resampling of the measured spectral samples to a discrete spectral positions separated according to the spectral channel interval within the spectral band
