Galaxy10 DECals Dataset
Galaxy10 DECaLS Dataset
==========================

Welcome! Galaxy10 DECals is a much improved version of our original `Galaxy10`_. The source code is here: https://github.com/henrysky/Galaxy10
Welcome! Galaxy10 DECaLS is a much improved version of our original `Galaxy10`_. The source code is here: https://github.com/henrysky/Galaxy10

The original Galaxy10 dataset was created with Galaxy Zoo (GZ) Data Release 2 where volunteers classify ~270k of SDSS galaxy images where ~22k of those images
were selected in 10 broad classes using volunteer votes. GZ later utilized images from `DESI Legacy Imaging Surveys`_ (DECals) with much better resolution and image quality.
Galaxy10 DECals has combined all three (GZ DR2 with DECals images instead of SDSS images and DECals campaign ab, c) results in ~441k of unique galaxies covered by DECals
where ~18k of those images were selected in 10 broad classes using volunteer votes with more rigorous filtering. Galaxy10 DECals had its 10 broad classes tweaked a bit so that
were selected in 10 broad classes using volunteer votes. GZ later utilized images from `DESI Legacy Imaging Surveys`_ (DECaLS) with much better resolution and image quality.

where ~18k of those images were selected in 10 broad classes using volunteer votes with more rigorous filtering. Galaxy10 DECaLS had its 10 broad classes tweaked a bit so that
each class is more distinct from each other and ``Edge-on Disk with Boxy Bulge`` class with only 17 images in original Galaxy10 was abandoned. The source code for this dataset is released
under this repositary so you are welcome to play around if you like, otherwise you can use the compiled Galaxy10 DECals with dowload link below.

The Legacy Surveys consist of three individual and complementary projects: the Dark Energy Camera Legacy Survey (DECaLS; Proposal ID #2014B-0404; PIs: David Schlegel and Arjun Dey), the Beijing-Arizona Sky Survey (BASS; NOAO Prop. ID #2015A-0801; PIs: Zhou Xu and Xiaohui Fan), and the Mayall z-band Legacy Survey (MzLS; Prop. ID #2016A-0453; PI: Arjun Dey). DECaLS, BASS and MzLS together include data obtained, respectively, at the Blanco telescope, Cerro Tololo Inter-American Observatory, NSF’s NOIRLab; the Bok telescope, Steward Observatory, University of Arizona; and the Mayall telescope, Kitt Peak National Observatory, NOIRLab. The Legacy Surveys project is honored to be permitted to conduct astronomical research on Iolkam Du’ag (Kitt Peak), a mountain with particular significance to the Tohono O’odham Nation.
