This is a sky simulation based on the SKADS S-cubed simulation of
Wilman et al. (2008). The simulated catalog includes Stokes Q and U
and gives a rotation measure that includes a random "internal"
component and a foreground. A small fraction of sources (2%) was
assigned large rotation measures, consistent with reality, but also
useful for testing purposes.

A 1 microJy cut-off was applied in ** total ** flux density (adding up
all components for FRI and FRII sources). The polarization information
is given per component. Different source components may have different
rotation measures. Each component of a source has the same
polarization angle at the reference frequency (1420 MHz).

Please note: A small fraction of sources in the S-cubed simulation
near the edge of the 20x20 field are incomplete because one or more
components are outside the defined area. None of these sources exists
in the polarization catalog because the code does not recognize these
exceptions. These were filtered out in a pre-processing step.

The output format of the catalog is as follows:

The IDL format for output is:
newSKADS_format = '(%"%d %6d %10d %2d %2d %2d %11.5f %11.5f %10.3f %10.6f
%9.3f %9.3f %9.3f %9.4f %9.4f %11.4e %11.4e %11.4e %11.4e %9.4f %9.4f
%9.4f %9.4f %10.4f %10.4f")'

There are lists for RQQ, FRI, FRII, and galaxies (normal+starburst; split
in ten pieces).
