What is 'sensor's filter function'? [message #55645]

I am trying to perform the atmospheric correction of an ALI image with
ENVI FLAASH addon.
FLAASH doesn't recognize this sensor, therefore I have to set the
sensor type to "Unknown MSI" and enter its characteristics manually.
It requires "Filter Function File", which is used to define the
sensor's spectral response.
I have found ALI spectral response functions.
How are these functions related to the "filter function"?
Are they the same?
