MODISA 250m processing info

Hi ocean colour forum, very quick question - sorry if this is posted somewhere obvious.
Can you tell me how the MODISA processing with l2gen implements 250m resolution processing? I'm assuming the 250m bands are used to interpolate the 1km bands, and if I'm correct, how is this done?
Thank you. :)

The 250m bands are not used in the interpolation, however, l2gen does do a bilinear interoplation the 1km (and 500m) bands to the 250m resolution when given the parameter resolution=250
