The catalog of true edge-on disk galaxies (Bizyaev et al., 2014)
is automatically selected from the Seventh Data Release of the Sloan Digital Sky Survey (SDSS).
It contains 5747 genuine edge-on galaxies after visual inspection of the g, r, i images of 14983 candidates.
The initiial sample were obtained with a criterion:
petroMag_g < 20
& isoA_g > 37.8
& isoA_g/isoB_g > 3
& -0.5 < dered_g - dered_r < 2
& -0.5 < dered_r - dered_r < 2
The visual inspection allows to split the initial sample on:
true edge-on galaxies (4768), non-edge-ons (8350) and objects with a complex structure (1865).
Since the initial automatic selection of the galaxy candidates did not include a significant number of the largest edge-on galaxies,
the final version of EGIS catalog incorporates edge-on candidates by supplying objects
from RFGC, RC3, EFIGI, and Galaxy Zoo that were found in the SDSS footprints.
