ABR/CBR presets lowpass frequency

I have been looking for this but wasn't able to find anything conclusive using the search function. How is the lowpass frequency determined in the alt-presets (ABR/CBR) ? Is there a look-up table or is it some sort of function of the specified bitrate?

In the current CVS, you'll find it in presets.c in libmp3lame.
