-Adding a channel
-===============
-
-After adding a system, a telescope and a laser to the database, you need to add a new channel. 
-To do this, click on the **HOI channels** in the *System settings* panel.
-This will take you to a page with a list of all availabe channels that are connected with your lidar systems. 
-This list should be empty if this is the first time you add a system. 
-
-To add a new channel to the database click on **Add HOI channel** at the top right of the screen.
-This will take you to a new page were you can fill in the needed information. As before, the fields in **bold**
-are mandatory and you will need to fill them before you can save you new system. 
-
-The fileds you have to fill here are more, as many of these are used during the processing of measurements.
-
-.. warning::
-
-   There is a last step, different from the previous cases, when saving a new channel. You need to connect your  channel with
-   a lidar system before you save, or else all your entry will be lost. Read carefully through this document (or directly
-   the :ref:`last section <connect-channel-to-system>`) to avoid any problems.
-   
-
-Fill in the fields
-------------------
-
-To start using the single calculus chain you will need to fill the following fields:
-
-Name
-   The name of the channel ex. "355", "1064 analog" etc.
-
-Telescope
-   The telescope that is used for this channel
-   
-Laser
-   The laser that is used for this channel
-
-Interference filter center
-   The center of the interference filter in nm
-   
-Interference filter FWHM
-   The FWHM of the interference filter in nm
-
-Emission wavelength
-   The emission wavelength of the laser used for this channel
-   
-Field of view
-   The field of view realated to this channel in mrad
-
-Raw range resolution
-   The raw range resolution of the measured data in m
-
-Dead time
-   The dead of the detector in ns. You should fill in this in case
-   of a photon counting detector.
-
-Trigger delay
-   The trigger delay value for the channel in ns. Fill in 0 if not needed.
-   
-Scattering mechanism
-   The scattering mechanism that is involved in this channel. Select the appropriate value from the drop-down list.
-
-Dead time correction type
-   The dead time correction type to be applied. Select *Not defined* if none needs to be defined.
-
-Background mode
-   The way to calculate the singal background. Select *Not defined* if none needs to be defined.
-
-Signal type
-   The type of the singal that is measured, ex. "elT" for total elastic, "vrRN2" for vibrational-rotational
-   Raman signal from Nitrogen melecules etc. See :ref:`signal-types` for details.
-   
-Detection mode
-   The detection mode of this channel.

-
-Connecting to a system
-----------------------
-
-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
-select your system from the drop-down list in the **System channels** area. 
-
-When you are done, press the **save** button at the bottom right of the page. 
-This will take you back to the list of your channels. 
-If everything went OK your new channel you just added should appear in the list.
