This was done for two reasons. First, when we looked a number of gaussian results, we saw that those with fits between 8.8 and 10.0 did not exhibit a convincing gaussian shape. Instead, they appeared to more spike like. Second, with the extension of the doppler drift range, our gaussian return rate would go up by a factor of five. Given that the majority of these would be false positive, we tightened up the threshold.
New graphics display the pulse detection algorithms.
On balance, this gives the project the best science for the CPU cycles used. We trimmed processing where we could to lessen the impact on execution time. This of course affects the stats. It will take longer to add to your results received statistic. There is also a great deal more variabilty in execution time with version 3.0.
