27 | // Digits consists of | |

29 | // - Ring ID | |
30 | // - Sector # | |
31 | // - Strip # | |
32 | // - ADC count in this channel | |

34 | // Digits consists of | |
35 | // - Detector # | |
36 | // - Ring ID | |
37 | // - Sector # | |
38 | // - Strip # | |
39 | // - Total energy deposited in the strip | |
40 | // - ADC count in this channel | |
41 | // | |
42 | // As the Digits and SDigits have so much in common, the classes | |
43 | // AliFMDDigit and AliFMDSDigit are implemented via a base | |
44 | // class AliFMDBaseDigit. | |

58 | // derived class from some base class - say AliFMDStrip, and the Digit | |
59 | // classes would (eventually) have derived from that as well. | |
60 | // However, ROOT doesn't do well with multiple inheritance, so I chose | |
61 | // not to anyway). | |
