// =============
//
// This macro can help to  find "hot" pixels firing too often
// or pixels firing too rarely. It plots camera displays showing how many 
// times the FADC integral of each pixel has been found to be above pedestal
// by 10, 20, 50, 100 or 200 ADC counts. As "pedestal"  we now use simply 
// the signal in the first ADC slice, which seemed reasonable from a first
// look at the available test data.
