The text file :bash:`infousedsat.txt` contains information required to extract the simulated variables required to compute the equivalent of satellite data.

The first line of the file gives the number of satellites. Even if no satellite data is to be used, :bash:`infousedsat.txt` must exist: it then contains only :bash:`0`. If the number of satellite is not zero, the following sets of lines are read for each satellite:
  - the name of the satellite (7 characters), its ID number (an integer between 1 and 100)
  - the maximum number of vertical levels in the satellite's vertical grid, the number of the formula to use for computimg the equivalent of the observations (see :doc:`the formulas implemented in the CIF</documentation/plugins/transforms/satellites>`)
