This is a posting summarizing Stars, Milky Way & Local Volume emails earlier today: Members respond to @jbosch and @RHL 's call for test data and development of metrics. I’ve tried to tag people whose usernames I know. We’re still new to community
Knut Olsen: @knutago
I am swamped through June, but after that would like to help with 1), using DECam data from the SMASH survey. I developed a crowding metric as part of the cadence white paper work, which I could revise to address this problem.
Alex Drliva-Wagner @kadrlica
I’m also happy to contribute to (1). I think that we can identify a
fair amount of DECam data available in crowded fields.
Christian Johnson (Clay Fellow, CfA) has reduced all of the very crowded Blanco DECam Bulge Survey data, using Daophot. He is collaborating with me, and we would be happy to provide or to reduce a challenge dataset.
Jeffrey Carlin: @jeffcarlin
I would also be happy to contribute both data and effort. We have HSC data from an ongoing survey of Local Volume (D ~ 2-4 Mpc) galaxies. The HSC/LSST stack doesn’t yet detect/measure sources in the crowded central regions of these galaxies, or in the bodies of the dwarf galaxy satellites we have discovered. These would be great testbeds for improvements to crowded-field techniques.
Peregrine McGehee shared thoughts on developing requirements which I have not copied here because I want to have them in a separate post. @pmmcgehee
