                    Table of intermodulation products

The left column quoted "#", holds the frequency, expressed in multiples of
the elementary frequency step.

It is a good idea to set the frequency of the first carrier at zero.

The next columns show output levels in decibels, relative to the zero dB
level (TWT saturation, 1 dB compression point):

- Column quoted "i" gives the individual carrier output level, generally
  smaller than the input level of the .MCR file, because of the non-linear
  amplifier compression.
- The two next columns quoted "2i-j" and "i+j-k" give the levels of third
  order intermodulation products, in 2fi-fj and fi+fj-fk respectively.
  When several intermodulation products with a same type have the same
  frequency, the power sum is displayed (so, the result is valid only if
  carriers are independent, namely they come from different oscillators).
- Column quoted "Total 3" gives, for every frequency, the total power of
  those two types of products.




- If the user has decided to also compute the fifth order intermodulation
  products, the corresponding columns are displayed, as well as a column
  showing the sum of powers of fifth order products, and a last column showing
  the sum of third and fifth order products.
  In this case, the screen width is too narrow to display the whole table,
  the user must shift the visible part with the Right and Left keys.
  After quitting the display, the user is proposed to save the table in the
  "RESU_MCR" file, in the repertory of temporary files.
