Optimum Orders for the Echelle
Reference Table of Echelle Orders
The following table of optimum orders for the Echelle grating is used by the
software to automatically select the best order for a given wavelength. It
is included here for reference and as a guide to which orders to explore if
you need to use a lower or higher order. Calculation of optimum orders and
the use of other orders are both discussed in the echelle
section
