This ASKAP data release includes a simulated polarisation observation. 

* The input model used was an updated version of the SKADS S3-SEX catalogue (Wilman et al 2008) provided by Jeroen Stil of the POSSUM team.
The additions to the SKADS catalogue are Q & U fluxes for each component plus a rotation measure made up of a random "internal" component 
and a foreground. 
* The sky model was used as input for a telescope simulation, which featured:
** The 2km core of the ASKAP configuration (ie. 30 antennas only)
** The effect of the phased-array feed was simulated by using 32 idealised beams, spaced in a rectangular grid 0.5deg apart 
(the arrangement is a 6×6 square, without the corners). 
** The total integration time was 8hr, with 10s integrations
** The spectral setup used 32 channels, each 8MHz in width, ranging from 1420MHz to 1172MHz
** Each channel was simulated and imaged separately, then combined into a cube.
** The preconditioning was Normalised Wiener filtering with robust = +0.25, Gaussian tapering with 27.6 x 27.6 arcsec.

We also provide the individual Stokes cubes for the restored image as separate cubes (each 1536x1536 pix x 32 channels).

Addition (Aug 2010): We have also provided the input catalogues. These were generated by Jeroen Stil, using the SKADS S3-SEX 
simulation as a starting point. There is a tarball containing the full set of catalogues, spanning 20x20 degrees (centred at 
ra,dec=0,0), and a smaller ascii file containing just those sources used to generate the model, with positions matching the 
images (centred at ra,dec=12:30,-45:00). (The initial version of this file contained just the sources in one portion of the 
field - this has been rectified.) There is also a README file included detailing the composition of the catalogue.

The data are located in the directory giant:/DATA/DELPHINUS_2/whi550/ASKAPsimulations/Polarisation/May2010 which can be accessed from 
most machines on the ATNF network. The directory contains the following files (each image being 1536x1536 pix x 4 stokes x 32 channels, 
except for the model, which is 4096x4096x4x32) which have self-explanatory names (the png image is of the full field in polarised flux):
