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. - -.. _connect-channel-to-system: - -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. - -
