Signal_Type
===========

In order to define the role of each channel, it has been decided to assign a number to each possible channel type.

For raw data, there are 2 types of signals: photon-counting channels (100 -> 109) and analog channels (110 -> 119).

- 100: Signal Rayleigh ON near Range Photon counting
- 101: Signal Rayleigh OFF near Range Photon counting
- 102: Signal Rayleigh ON far Range Photon counting
- 103: Signal Rayleigh OFF far Range Photon counting
- 104: Signal Raman ON Photon counting
- 105: Signal Raman OFF Photon counting
- 110: Signal Rayleigh ON near Range Analogic
- 111: Signal Rayleigh OFF near Range Analogic
- 112: Signal Rayleigh ON far Range Analogic
- 113: Signal Rayleigh OFF far Range Analogic
- 114: Signal Raman ON Analogic
- 115: Signal Raman OFF Analogic

When merging channels together, a new type of signal is created:

- 120: Signal Rayleigh ON photon counting near/far range (100/102)
- 121: Signal Rayleigh OFF photon counting near/far range (101/103)
- 122: Signal Rayleigh ON analogical near/far range (110/112)
- 123: Signal Rayleigh OFF analogical near/far range (111/113)

Finally, when creating the ozone signal, a new type of signal is then created:

- 130: Ozone Rayleigh near range photon counting (100/101)
- 131: Ozone Rayleigh far range photon counting (102/103)
- 132: Ozone Raman photon counting (104/105)
- 133: Ozone Rayleigh near range analogical (110/111)
- 134: Ozone Rayleigh far range analogical (112/113)
- 135: Ozone Raman analogical (114/115)
- 136: Ozone Rayleigh photon counting near/far range (120/121)
