In some of the analysis programs in MIDAS the graphic cursor is a powerful
tool. For example, using the cursor one can retrieve wavelengths and
line intensities in a plotted spectrum, integration of emission or
absorption lines over a wavelength range selected by the cursor, compute
the line width and center, etc. With the general GET/GCURSOR command
the user can retrieve information from plotted data and store this in a
table. Listed below are some of the core and application commands which
use cursor interaction. Many additional graphics commands, including
those that use cursor interaction, are available in the various contexts,
e.g. SPEC and ECHELLE.
