| | 1 | difference image concerns: |
| | 2 | |
| | 3 | * normalizations: |
| | 4 | * are they correct? |
| | 5 | * significant coupling between normalization and other kernel terms |
| | 6 | * ringing -- there is significant ringing left behind in difference of images with PS1_V1 PSF shapes |
| | 7 | * is the basis function able to represent the actual observed differences sufficiently? |
| | 8 | * is the observed ringing the result of the coupling to the normalization? |
| | 9 | * is the observed ringing due to the degeneracy between basis terms? |
| | 10 | * basis function orthogonality |
| | 11 | * does the non-orthogonal nature of the Alard-Lupton kernels increase sensitivity to noise and false positives? |
| | 12 | * can we choose a more-orthogonal basis set? |
| | 13 | * span of basis set |
| | 14 | * how can we choose a set of kernels that spans a sufficient range? |
| | 15 | * can the Alard-Lupton basis set cover a wide enough range of structures? |
| | 16 | * weighting? |
| | 17 | * windowing? |
| | 18 | * dual convolution -- strange results with power going to non-radial terms |
| | 19 | |
| | 20 | Some specific bugs identified |
| | 21 | |
| | 22 | * normalizations were failing for 1D convolutions |
| | 23 | |
| | 24 | * the wrong preCalc element was being used in a certain context related to Dual |
| | 25 | |
| | 26 | * the peak pixel is rediscovered, changing the center by 1 pixel for well-centered stars (this is not technically a bug, but |
| | 27 | makes it difficult to interpret the chi-square images) |
| | 28 | |
