论文摘要
Hectomap是对95,403个星系的密集红移调查，主要基于MMT光谱，中间红移$ z = 0.345 $。该调查覆盖了54.64平方度的1.5 $^\ Circ $宽地带，北方天空的偏心为43.25 $^\ Circ $。我们报告红移，频谱指标D $ _ {n} $ 4000和恒星质量。红色选定的调查为55,962个星系为81 \％，$（g-r）> 1 $和$ r <20.5 $;对于32,908个星系，$（g-r）> 1 $，$（r-i）> 0.5 $和$ 20.5 <r <r <21.3 $的32,908个星系为72 \％。调查基础SDSS光度法与HSC-SSP光度法的比较表明，Hectomap基于任何两位光度系统提供了完全有限的限制调查。我们更新了HSC-SSP光度光度与Hectopspspomap光谱红移之间的比较；比较表明，在第二个数据释放和第三个数据之间，HSC-SSP光度降轴有所改善。 Hectomap是检查静态星系人群（占调查的63％），星系簇和宇宙网络的基础。 HSC-SSP调查完全涵盖了HECTOMAP，从而实现了各种强和弱的镜头研究。
HectoMAP is a dense redshift survey of 95,403 galaxies based primarily on MMT spectroscopy with a median redshift $z = 0.345$. The survey covers 54.64 square degrees in a 1.5$^\circ$ wide strip across the northern sky centered at a declination of 43.25$^\circ$. We report the redshift, the spectral indicator D$_{n}$4000, and the stellar mass. The red selected survey is 81\% complete for 55,962 galaxies with $(g-r) > 1$ and $r <20.5$; it is 72\% complete for 32,908 galaxies with $(g-r) > 1$, $(r-i) > 0.5$ and $20.5 < r < 21.3$. Comparison of the survey basis SDSS photometry with the HSC-SSP photometry demonstrates that HectoMAP provides complete magnitude limited surveys based on either photometric system. We update the comparison between the HSC-SSP photometric redshifts with HectoMAP spectroscopic redshifts; the comparison demonstrates that the HSC-SSP photometric redshifts have improved between the second and third data releases. HectoMAP is a foundation for examining the quiescent galaxy population (63\% of the survey), clusters of galaxies, and the cosmic web. HectoMAP is completely covered by the HSC-SSP survey, thus enabling a variety of strong and weak lensing investigations.
