Make air mass curve (dialog)
============================

The "Make air mass curve" dialog is used to create a curve of air mass coefficients
and altitudes as a function of time. These values to useful in data post-processing to compute
the extinction coefficients.


Activating the dialog
---------------------

The dialog can be activated:

#. from the main menu: :menuselection:`Make --> Air mass curve`.
