The kernels were created using a Fourier technique which requires a certain fiddling to get good results. While these kernels are approximate as a result, they should give quite good results. They have not been extensively tested, especially the IRAC-to-IRAC kernels. Feedback to Karl Gordon (kgordon@stsci.edu) is appreciated.

If you use these kernels in a paper, please reference Gordon et al. (2008, ApJ, 682, 336) and Aniano et al. (2011, PASP, 123, 1218).
