Workspace Variable met_mm_backend

Backend description for meteorological millimeter sensors with passbands.

This is a compact description of a passband-type sensor, e.g. AMSU-A. The matrix
contains one row for each instrument channel. Each row contains four elements:

  LO position [Hz]
  first offset from the LO [Hz]
  second offset from the LO+offset1 [Hz]
  channel width [Hz]

                          LO
                           |
               offset1     |    offset1
           ----------------+----------------
           |                               |
           |                               |
  offset2  |  offset2             offset2  |  offset2
  ---------+---------             ---------+---------
  |                 |             |                 |
  |                 |             |                 |

width             width         width             width

For a sensor with 1 passband, offset1 and offset2 are zero.
For a sensor with 2 passbands, only offset2 is zero.

Usage: Set by the user.

Unit: All entries in Hz.

Size: [number of channels, 4]

Group: Matrix
