Elton and Fernando:

I corrected the dynamic range of BCAL according to Irina's results (from
gluex-doc-1474 note). The attachment contains "zoomed" plots from the note
pages 31 and 38 (for easy reading of the spectra edges).

Please use the corrected numbers for your references in the future.

Thank you,
Andrei
