| 5 | | The original diff_sn diff_r plots were difficult to read due to the overlays. I've split these plots up into direct density plots, which was what the original plots were intended to show. As before, these plot diff_r values as a function of the ratio of the diff_sn to the detection S/N. The first table shows the R and S/N for the Positive measurements. The second shows the same figures for the Minus measurements. |

| | 7 | These plots show the following set of features: |
| | 8 | 1. Real asteroids form a "ridge" of approximately constant DSNR for a small range of R values in the Positive measurements. This ridge overlays a population of "stellar like" objects that have a detection in the warp image. In the Minus measurements, this ridge maintains the DSNR value but shifts to a larger R value, indicating the the source on the inverse image is further away. |
| | 9 | 2. In the unconvolved difference, the ridge in DSNR of likely asteroids seems to separate from the group containing largely "stellar like" objects, with the asteroids having DSNR ~ 1.0, and the stars DSNR > 3. |
| | 10 | 3. The MOPS cut in the Positive measurements does work reasonably for the convolved difference, but is overly permissive in the unconvolved case. This is not the case for the (warp warp) Minus measurements, as the true asteroids tend to fall at large R values with the same lower DSNR. |
| | 11 | 4. The unconvolved Warp-Stack difference does not provide much discrimination between stars and asteroids in DSNR/R space. This is especially true in the Minus measurements, where true asteroids are associated largely at random DSNR values. |
