* Attenuations command file as used by MCPROD for processing of
* D2O (LETA) data. Do not edit without the permission of the MCPROD Group.
*------------------------------------------------------------
* Command file to set optical parameters
* Based on QOCAFit results
* This file must be read in before any version of media.dat
* File produced: Tue Jan 10 14:39:27 2006
* Contact: O. Simard (Carleton)
*------------------------------------------------------------
* Rayleigh scale factor is change from 25degC (SNOMAN) to
* 11degC, the average SNO water temperature reported by
* the water group (Tony Noble, 2000).*
* The absorption numbers were calculated from the QOCAFit
* attenuation results by subtracting the contribution of
* Rayleigh scattering to the prompt attenuation.
*------------------------------------------------------------
* Nominal fit results for 4ns time window.
* Using nominal alpha_d2o(337nm).
*------------------------------------------------------------
* Rayleigh Scattering Scaling Factor in D2O
* brought back to 1.000.
