Comments: Date: march, 1999                                                            
Site: European Photo Reactor (EUPHORE), Valencia/Spain
the spectrum was assembled from 2 individual 35dmba spectra recorded with an ACTON Spectra Pro 500 and 1200l/mm grating and
1024pixel Hamamatsu PDA
spectral alignment was done according to the linear dispersion determined for the two spectral ranges:
spectral range I:      304.842 - 269.973 dispersion:     0.03883 Accuracy:       9%
spectral range II:     269.969 - 225.255 dispersion:     0.03891 Accuracy:       10%
sigma was calculated from the known amounts of dmba which were added to EUPHORE (assuming V = 187 m^3)
