Columns

Name Type UCD Unit Description
galaxy int meta.id

CAVITY ID [5]
GZ1Ell float meta.code
src.morph.type

GZ1 catalogue of ELLIPTICAL classified galaxy. Ellipticals are marked as 1, else as 0 [1]
GZ1S float meta.code
src.morph.type

GZ1 catalogue of SPIRAL classified galaxy. Spirals are marked as 1, else as 0 [1]
GZ1U float meta.code
src.morph.type

GZ1 catalogue of UNCERTAIN classified galaxy. Galaxies with high uncertainty in classification are marked as 1, else as 0 [1]
GZ2class char meta.code.class
src.morph.type

The most common morphology for galaxies among different classifications [2]
GZ2formula float src.morph.type

GZ2 morphology classification [2]
pdominant float stat.value

Weighted fraction of GZ2 votes for “dominant bulge”. Galaxies with dominant bulge have higher values [2]
pnobulge float stat.value

Weighted fraction of GZ2 votes for “no bulge”. Galaxies with no bulge have higher values [2]
pobvious float stat.value

Weighted fraction of GZ2 votes for “obvious bulge”. Galaxies with obvious bulge have higher values [2]
probaEarly float stat.probability

Probability of a galaxy being a early-type galaxy (’probaEarly’ = ’probaE’ + ’probaS0’) [3]
probaEll float stat.probability

Probability of a galaxy being elliptical [3]
probaLate float stat.probability

Probability of a galaxy being a late-type galaxy (’probaLate’ = ’probaSab’ + ’probaScd’) [3]
probaS0 float stat.probability

Probability of a galaxy being lenticular [3]
probaSab float stat.probability

Probability of a galaxy being spiral Sa or Sb type [3]
probaScd float stat.probability

Probability of a galaxy being spiral Sc or Sd type [3]
TType_DS float meta.code.class
src.morph.type

T-type, early–type galaxies are marked with values ≤ 0 and late–type–galaxies with values > 0 [4]
