10// MRawPixel
11//
12// One Event in the Camera of MAGIC consists of measurements of different
13// Photomultiplier. The measurements are taken with FADCs. So the raw
14// informations of one pixel are the ADC values of the FADCs. MAGIC will
15// measure the amplitude of one Photomulitplier in different branches
16// - one high and one low gain branch. The first is for small signals, the
17// other for big signals. With this method it is possible to increase the
18// dynamic range.
19//
20// The Class MRawPixel is used to manage this raw information.
21//
22// The data members are described in detail here:
23//
24// ---------
25//
26// UShort_t PixelId ;
27//
28// This is to identify the Pixel.
29// The Camera consists of CAMERA_PIXELS Pixels. Each one has a specific Id.
30// The center of the camera is zero and a spiral numbering is chosen.
31//
32// To reduce the amount of data, we store the information of the
33// low-gain-branch of the Fadc´s only if there is a signal in. Then the
34// PixelId is:
35// PixelId = 10000 + PixelId .
36//
37// For the high gain Fadc values the rule is:
38// PixelId = PixelId .
39//
40//
41// ---------
42//
43// UChar_t PixelStatus ;
44//
45// The PixelStatus may contain information if the Pixel has triggered
46// this event. Also the kind of gain-branch (high or low) may be indicated
47// by one bit of the PixelStatus. etc
48//
49// ---------
50//
51// UChar_t Fadc[ kFADC_SLICES ] ;
52//
53// The values of kFADC_SLICES fadc-slices. This is the information of the
54// measured ADC values for one branch (high gain or low gain). The typ of
55// branch is indicated in the usPixelNumber and in the PixelStatus.
