The Fornax Deep Survey (FDS), an imaging survey in the u', g', r', andi'-bands, has a supreme resolution and image depth compared to the previousspatially complete Fornax Cluster Catalog (FCC). Our new data allows us tostudy the galaxies down to r'-band magnitude m$_{r'}\approx$21 mag(M$_{r'}\approx$-10.5 mag). These data provide an important legacy dataset tostudy the Fornax cluster. We aim to present the Fornax Deep Survey (FDS) dwarfgalaxy catalog, focusing on explaining the data reduction and calibrations,assessing the quality of the data, and describing the methods used for definingthe cluster memberships for the catalog objects. As a first step we used theSExtractor fine-tuned for dwarf galaxy detection, to find galaxies from the FDSdata, covering a 26 deg$^2$ area of the main cluster, and the area around theFornax A substructure. We made 2D-decompositions of the identified galaxiesusing GALFIT. We used color-magnitude, luminosity-radius andluminosity-concentration relations to separate the cluster galaxies from thebackground galaxies. We then divided the cluster galaxies into early- andlate-type galaxies according to their morphology and gave first ordermorphological classifications. Our final catalog includes 14,095 galaxies. Weclassify 590 galaxies as being likely Fornax cluster galaxies, of which 564 aredwarfs (M$_{r'}$ > -18.5 mag) consisting our Fornax dwarf catalog. Of thecluster dwarfs we classify 470 as early-types, and 94 as late-type galaxies.Our final catalog reaches its 50% completeness limit at magnitude M$_{r'}$ =-10.5 mag and surface brightness $\bar{\mu}_{e,r'}$ = 26 mag arcsec-2, which isapproximately three magnitudes deeper than the FCC. Based on previous works andcomparison with a spectroscopically confirmed subsample, we estimate that ourfinal Fornax dwarf galaxy catalog has < 10% contamination from the backgroundobjects.
