//==========
// MRawPixel 
//    
// One Event in the Camera of MAGIC consists of measurements of different
// Photomultiplier. The measurements are taken with FADCs. So the raw 
// informations of one pixel are the ADC values of the FADCs. MAGIC will
// measure the amplitude of one Photomulitplier in different branches 
// - one high and one low gain branch. The first is for small signals, the 
// other for big signals. With this method it is possible to increase the 
// dynamic range.  
//
// The Class MRawPixel is used to manage this raw information. 
//
// The data members are described in detail here: 
//
// ---------
//
// UShort_t     usPixelId     ;   
//
// This is to identify the Pixel.
// The Camera consists of CAMERA_PIXELS Pixels. Each one has a specific Id.
// The center of the camera is zero and a spiral numbering is chosen.
//
// To reduce the amount of data, we store the information of the 
// low-gain-branch of the Fadc´s only if there is a signal in. Then the 
// usPixelId is:
//                   usPixelId = 10000 + PixelId   . 
//
// For the high gain Fadc values the rule is:
//                   usPixelId = PixelId . 
//
//
// ---------
//
// UChar_t      ucPixelStatus ;   
//
// The PixelStatus may contain information if the Pixel has triggered 
// this event. Also the kind of gain-branch (high or low) may be indicated 
// by one bit of the ucPixelStatus. etc
//
// ---------
//
// UChar_t      aucFadc[ FADC_SLICES ]  ; 
//
// The values of FADC_SLICES fadc-slices. This is the information of the 
// measured ADC values for one branch (high gain or low gain). The typ of 
// branch is indicated in the usPixelNumber and in the ucPixelStatus.
