- H3 Spectroscopic Survey [ arXiv:1907.07684 | h3survey.rc.fas.harvard.edu]
- spectrophotometric distances for 200,000 stars to r=18.
- Hectochelle instrument at the MMT,resolution R~23,000 spectra covering the wavelength range 5150A-5300A.
- The survey is optimized for stellar halo science and therefore focuses on high Galactic latitude fields (|b|>30 deg.), sparsely sampling 15,000 sq. degrees.
