Complementarity of LSST and WFIRST: Regarding Object Blending
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Many aspects of the complementarity between LSST and WFIRST have been discussed in the WFIRST-AFTA Final Report (Spergel et al. 2013) and accepted within the community. For example, LSST’s six optical filters (u,g,r,i,z,y) and WFIRST’s four infrared filters (Y,J,H,F184)1, which will achieve effectively the same depth, will be highly complementary for photometric redshift estimation. However, the important subject of object blending has been absent from many of these discussions. In this letter we wish to focus on the complementarity of LSST and WFIRST in specific regards to object blending issues. Both how blending will affect the naively assumed complementarity of the two surveys as well as how the complementarity of the two surveys can mitigate the detrimental effects of object blending.
