We have finished the first complete analysis of the LIGO S3 data set. Based on this, the data preparation and cleaning process have been modified to remove a number of instrumental artifacts that appeared in the post-processing stage, and a new data set has been prepared. This new data set uses the final S3 time-domain calibration and also includes a number of 'software simulated' fake source signals. After we have completed analysis of this final S3 data set (a few weeks) we will to move on to the new and more sensitive S4 data set.
