ppSub Modifications September 2010

(Up to the IPP for PS1)

This page compares results from several versions of the ppSub DUAL convolution process.

Each page shows the input images, the difference image, the convolved image (for the smaller input image in general), and the convolution kernel pair.

• Modifications as of 2010.09.18 : These use penalty of 4e-6, and are from branches/eam_branches/ipp-20100823, r29224)

• Modifications as of 2010.08.23 : These correct the normalization (better apertures) and use different penalties for A and B. Code is from tags/ipp-20100823, r29167)

• Modifications as of 2010.07.01 : These use the algorithm from the start of demo month, tags/ipp-20100701, r28945)

• Modifications as of 2010.09.18, v0 : These use penalty of 5e-7, and are from branches/eam_branches/ipp-20100823, r29224)

• Modifications as of 2010.09.18, v1 : These use penalty of 1e-6, and are from branches/eam_branches/ipp-20100823, r29224)

• Modifications as of 2010.09.18, v2 : These use penalty of 2e-6, and are from branches/eam_branches/ipp-20100823, r29224)

On each of the pages above, a single version of the IPP ppSub code and the penalty value was used for a large number of image pairs. Each image is a simple grid of stars with a Gaussian PSF of different sizes and shapes. The table below gives the relevant parameters for each of the input images. The names of the difference image jpegs identifies the image pair:

For example, ​http://ipp0022.ifa.hawaii.edu/ippData/ppsub.20100918/diff.gg.20100701/diff.gg.23.16.00.ex.jpg

In the name of the file, diff.gg.23.16.00.ex.jpg, The 3 2-digit pairs give (in order) the ID of the first image, the ID of the second image, and the version of the analysis. The version on matters for the 2010.09.18 data, for which 4 separate penalties are shown. We have (tentatively?) chosen the 03 version of the penalty (4e-6). To see these names, mouse over the diff jpeg and look at the name of the link.
