PARAMETER NCAP_AFC /
CH.0.PROR-1.ACT.DAYNITE -1
CH.2010.PROR-1.RORIN.DAYNITE 0.4
CH.2010.PROR-1.ELECTRICITY.DAYNITE 1

The first NCAP_AFC entry is just a flag for triggering independent NCAP_AFC equations.  
Normally, NCAP_AFC equations are defined for the whole PG group, and in that case the normal EQ_CAPACT equations are not generated at all. But in this case it is more convenient to keep the EQ_CAPACT equations for defining the availability factor for the storage capacity.  Therefore, the flag  CH.0.PROR-1.ACT.DAYNITE -1.

The second NCAP_AFC entry defines the maximum DAYNITE input availability factor: The input flow is assumed evenly distributed, at the level of 40% of the turbine capacity. So, the value is 0.4. You could also define timeslice-specific values for it.  

The third NCAP_AFC entry defines the maximum DAYNITE output availability factor, which is assumed 100% of the capacity. Thus the value is 1.

PARAMETER NCAP_AF /
CH.2010.PROR-1.ANNUAL.UP 0.15

Finally this NCAP_AF parameter defines the pond storage availability factor.  As mentioned, the size is 0.15 of the nominal daily maximum production, and thus the value is 0.15.
