| | 3 | Comparison of SAS processing with current tag and with proposed updates. The first two columns show the apples-to-apples comparison of the current IPP tag and the proposed changes to the trunk. This shows that the improvement in the input rejection is roughly equal in the two versions of the code, with the SAS123 showing a slight favor to the proposed changes (30% improved input fraction compared with 20% that did not). The increase in the fill factor is largely a result of switching the safety flag to false, and not due to the increase in input number. The final column shows the comparison between the proposed changes and the original SAS_v8 processing from 2012-07-19. This processing did not have the stack input filtering enabled to the degree it currently is, and as a result, only failures in the PSF-matching phase contribute to the input rejection. Without this filtering, the fraction of inputs used is obviously higher. This raises the question of whether input filtering is really helpful for 3pi stacks. |
