    keyword=clock scalers in replay

    Rates of 1024 clock (T8) left_clkcount and 104K clock (T25) left_clk104K look inconsistent in ONLANA replay of data.

    Definition in onlana.odef for 104K clock is erroneous begin scalers left # 1024 Hz clock clkcount 3 7 counts clk104K 2 24 counts look in .../dvcs/scaler/scaler.map # directives for Left HRS ... xscaler-pagename Left 0:'L-HRS LeCroy Scaler' xscaler-pagename Left 1:'L-HRS Normalization Scaler ++ gated by helicity PLUS' xscaler-pagename Left 2:'L-HRS Normalization Scaler -- gated by helicity MINUS' xscaler-pagename Left 3:'L-HRS Normalization (NOT gated by hel)' xscscaler

    slot 3 contains the ungated scalers slot 2 is the virtual helicity MINUS gated scaler

    changed onlana.odef to slot 3 for clk104K begin scalers left # 1024 Hz clock clkcount 3 7 counts # clk104K 2 24 counts ##slot 2 is the helicity MINUS gated scaler 22/10/10 CEH clk104K 3 24 counts
