binietoglou@7: Adding a channel
binietoglou@2: ===============
binietoglou@2: 
binietoglou@7: After adding a system, a telescope and a laser to the database, you need to add a new channel. 
binietoglou@7: To do this, click on the **HOI channels** in the *System settings* panel.
binietoglou@7: This will take you to a page with a list of all availabe channels that are connected with your lidar systems. 
binietoglou@7: This list should be empty if this is the first time you add a system. 
binietoglou@7: 
binietoglou@7: To add a new channel to the database click on **Add HOI channel** at the top right of the screen.
binietoglou@7: This will take you to a new page were you can fill in the needed information. As before, the fields in **bold**
binietoglou@7: are mandatory and you will need to fill them before you can save you new system. 
binietoglou@7: 
binietoglou@7: The fileds you have to fill here are more, as many of these are used during the processing of measurements.
binietoglou@7: 
binietoglou@7: .. warning::
binietoglou@7: 
binietoglou@7:    There is a last step, different from the previous cases, when saving a new channel. You need to connect your  channel with
binietoglou@7:    a lidar system before you save, or else all your entry will be lost. Read carefully through this document (or directly
binietoglou@7:    the :ref:`last section <connect-channel-to-system>`) to avoid any problems.

binietoglou@7: Fill in the fields
binietoglou@7: ------------------
binietoglou@7: 
binietoglou@7: To start using the single calculus chain you will need to fill the following fields:
binietoglou@7: 
binietoglou@7: Name
binietoglou@7:    The name of the channel ex. "355", "1064 analog" etc.
binietoglou@7: 
binietoglou@7: Telescope
binietoglou@7:    The telescope that is used for this channel
binietoglou@7:    
binietoglou@7: Laser
binietoglou@7:    The laser that is used for this channel
binietoglou@7: 
binietoglou@7: Interference filter center
binietoglou@7:    The center of the interference filter in nm
binietoglou@7:    
binietoglou@7: Interference filter FWHM
binietoglou@7:    The FWHM of the interference filter in nm
binietoglou@7: 
binietoglou@7: Emission wavelength
binietoglou@7:    The emission wavelength of the laser used for this channel
binietoglou@7:    
binietoglou@7: Field of view
binietoglou@7:    The field of view realated to this channel in mrad
binietoglou@7: 
binietoglou@7: Raw range resolution
binietoglou@7:    The raw range resolution of the measured data in m
binietoglou@7: 
binietoglou@7: Dead time
binietoglou@7:    The dead of the detector in ns. You should fill in this in case
binietoglou@7:    of a photon counting detector.
binietoglou@7: 
binietoglou@7: Trigger delay
binietoglou@7:    The trigger delay value for the channel in ns. Fill in 0 if not needed.
binietoglou@7:    
binietoglou@7: Scattering mechanism
binietoglou@7:    The scattering mechanism that is involved in this channel. Select the appropriate value from the drop-down list.
binietoglou@7: 
binietoglou@7: Dead time correction type
binietoglou@7:    The dead time correction type to be applied. Select *Not defined* if none needs to be defined.
binietoglou@7: 
binietoglou@7: Background mode
binietoglou@7:    The way to calculate the singal background. Select *Not defined* if none needs to be defined.
binietoglou@7: 
binietoglou@7: Signal type
binietoglou@7:    The type of the singal that is measured, ex. "elT" for total elastic, "vrRN2" for vibrational-rotational
binietoglou@7:    Raman signal from Nitrogen melecules etc. See :ref:`signal-types` for details.
binietoglou@7:    
binietoglou@7: Detection mode
binietoglou@7:    The detection mode of this channel.

binietoglou@7: Connecting to a system
binietoglou@7: ----------------------
binietoglou@7: 
binietoglou@7: 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
binietoglou@7: select your system from the drop-down list in the **System channels** area. 
binietoglou@7: 
binietoglou@7: When you are done, press the **save** button at the bottom right of the page. 
binietoglou@7: This will take you back to the list of your channels. 
binietoglou@7: If everything went OK your new channel you just added should appear in the list.
