4 Walk-through of adding a channel. |
4 After adding a system, a telescope and a laser to the database, you need to add a new channel. |
|
5 To do this, click on the **HOI channels** in the *System settings* panel. |
|
6 This will take you to a page with a list of all availabe channels that are connected with your lidar systems. |
|
7 This list should be empty if this is the first time you add a system. |
|
8 |
|
9 To add a new channel to the database click on **Add HOI channel** at the top right of the screen. |
|
10 This will take you to a new page were you can fill in the needed information. As before, the fields in **bold** |
|
11 are mandatory and you will need to fill them before you can save you new system. |
|
12 |
|
13 The fileds you have to fill here are more, as many of these are used during the processing of measurements. |
|
14 |
|
15 .. warning:: |
|
16 |
|
17 There is a last step, different from the previous cases, when saving a new channel. You need to connect your channel with |
|
18 a lidar system before you save, or else all your entry will be lost. Read carefully through this document (or directly |
|
19 the :ref:`last section <connect-channel-to-system>`) to avoid any problems. |

22 Fill in the fields |
|
23 ------------------ |
|
24 |
|
25 To start using the single calculus chain you will need to fill the following fields: |
|
26 |
|
27 Name |
|
28 The name of the channel ex. "355", "1064 analog" etc. |
|
29 |
|
30 Telescope |
|
31 The telescope that is used for this channel |
|
32 |
|
33 Laser |
|
34 The laser that is used for this channel |
|
35 |
|
36 Interference filter center |
|
37 The center of the interference filter in nm |
|
38 |
|
39 Interference filter FWHM |
|
40 The FWHM of the interference filter in nm |
|
41 |
|
42 Emission wavelength |
|
43 The emission wavelength of the laser used for this channel |
|
44 |
|
45 Field of view |
|
46 The field of view realated to this channel in mrad |
|
47 |
|
48 Raw range resolution |
|
49 The raw range resolution of the measured data in m |
|
50 |
|
51 Dead time |
|
52 The dead of the detector in ns. You should fill in this in case |
|
53 of a photon counting detector. |
|
54 |
|
55 Trigger delay |
|
56 The trigger delay value for the channel in ns. Fill in 0 if not needed. |
|
57 |
|
58 Scattering mechanism |
|
59 The scattering mechanism that is involved in this channel. Select the appropriate value from the drop-down list. |
|
60 |
|
61 Dead time correction type |
|
62 The dead time correction type to be applied. Select *Not defined* if none needs to be defined. |
|
63 |
|
64 Background mode |
|
65 The way to calculate the singal background. Select *Not defined* if none needs to be defined. |
|
66 |
|
67 Signal type |
|
68 The type of the singal that is measured, ex. "elT" for total elastic, "vrRN2" for vibrational-rotational |
|
69 Raman signal from Nitrogen melecules etc. See :ref:`signal-types` for details. |
|
70 |
|
71 Detection mode |
|
72 The detection mode of this channel. |
|

76 Connecting to a system |
|
77 ---------------------- |
|
78 |
|
79 Before you finish, you need to attach your channel to one of your systems. To do this, go at the bottom of the page and |
|
80 select your system from the drop-down list in the **System channels** area. |
|
81 |
|
82 When you are done, press the **save** button at the bottom right of the page. |
|
83 This will take you back to the list of your channels. |
|
84 If everything went OK your new channel you just added should appear in the list. |
