  Modified:    lib/modes psych_16.h psych_44.h psych_8.h
  Log:
  Lower absolute ATH to no more than -130dB, -140 nominal.  Carsten has
  found enough conterexamples at this point to disprove the rationale
  for a lowest-possible ATH in masking; the only value it has left is to
  give a bottom end to the dB range to avoid FP underflows.
