Dear Colleagues,

I have calculated tables using new Bartol flux.
They are in files:

vaxgs::disk$macro2:[stanislav]dfXXY12.dat,

where XX stands for neutrino interactions and Y does for muon
propagation.

XX = 11 cross section with PDF by EHLQ (1984,erratum 1986)
XX = 21 cross section with PDF by Morfin anf Tung (1991)
XX = 31 cross section with PDF by Ownes (1991)
XX = 41 cross section according to parameterization by
Gaisser and Stanev (1985);

Y = 1 muon propagation in Baksan rock
Y = 2 dE/dx = a + b*E (a=2.0E-3, b=3.9E-6)
Y = 3 muon propagation in standard rock according to muon
energy loss by Lohman et al.(1985)

The new Bartol flux gains expected effect small about 2.5%.
The table below shows comparision of integrated muon fluxes (Emu>1GeV)
averaged over downward hemisphere calculated with old and new Bartol
neutrino fluxes.

The estimation of number of events expected with MACRO gives
factor 1.027 relative to previous value for muon propagation in
standard rock and Morfin and Tung parton density functions.

Median neutrino energy for events detected by MACRO changed from
~49GeV to 53GeV.
