Adding a channel
ulalume3@11:
After adding a system, a telescope and a laser to the database, you need to add a new channel.
ulalume3@11: To do this, click on the HOI channels in the System settings panel.
ulalume3@11: This will take you to a page with a list of all availabe channels that are connected with your lidar systems.
ulalume3@11: This list should be empty if this is the first time you add a system.
ulalume3@11:
To add a new channel to the database click on Add HOI channel at the top right of the screen.
ulalume3@11: This will take you to a new page were you can fill in the needed information. As before, the fields in bold
ulalume3@11: are mandatory and you will need to fill them before you can save you new system.
ulalume3@11:
The fileds you have to fill here are more, as many of these are used during the processing of measurements.

Warning
ulalume3@11:
There is a last step, different from the previous cases, when saving a new channel. You need to connect your channel with
ulalume3@11: a lidar system before you save, or else all your entry will be lost. Read carefully through this document (or directly
ulalume3@11: the last section) to avoid any problems.

Fill in the fields
ulalume3@11:
To start using the single calculus chain you will need to fill the following fields:
ulalume3@11:
ulalume3@11: - Name
ulalume3@11: - The name of the channel ex. “355”, “1064 analog” etc.
ulalume3@11: - Telescope
ulalume3@11: - The telescope that is used for this channel
ulalume3@11: - Laser
ulalume3@11: - The laser that is used for this channel
ulalume3@11: - Interference filter center
ulalume3@11: - The center of the interference filter in nm
ulalume3@11: - Interference filter FWHM
ulalume3@11: - The FWHM of the interference filter in nm
ulalume3@11: - Emission wavelength
ulalume3@11: - The emission wavelength of the laser used for this channel
ulalume3@11: - Field of view
ulalume3@11: - The field of view realated to this channel in mrad
ulalume3@11: - Raw range resolution
ulalume3@11: - The raw range resolution of the measured data in m
ulalume3@11: - Dead time
ulalume3@11: - The dead of the detector in ns. You should fill in this in case
ulalume3@11: of a photon counting detector.
ulalume3@11: - Trigger delay
ulalume3@11: - The trigger delay value for the channel in ns. Fill in 0 if not needed.
ulalume3@11: - Scattering mechanism
ulalume3@11: - The scattering mechanism that is involved in this channel. Select the appropriate value from the drop-down list.
ulalume3@11: - Dead time correction type
ulalume3@11: - The dead time correction type to be applied. Select Not defined if none needs to be defined.
ulalume3@11: - Background mode
ulalume3@11: - The way to calculate the singal background. Select Not defined if none needs to be defined.
ulalume3@11: - Signal type
ulalume3@11: - The type of the singal that is measured, ex. “elT” for total elastic, “vrRN2” for vibrational-rotational
ulalume3@11: Raman signal from Nitrogen melecules etc. See Signal types for details.
ulalume3@11: - Detection mode
ulalume3@11: - The detection mode of this channel.

Connecting to a system
ulalume3@11:
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
ulalume3@11: select your system from the drop-down list in the System channels area.
ulalume3@11:
When you are done, press the save button at the bottom right of the page.
ulalume3@11: This will take you back to the list of your channels.
ulalume3@11: If everything went OK your new channel you just added should appear in the list.
