J/AJ/111/42 J/AJ/111/42 Galaxies in Abell 168 A Tomita F E Nakamura T Takata K Nakanishi T Takeuchi K Ohta T Yamada Astron. J. 111 42 1996 1996AJ....111...42T III/174 : Dressler's catalog of morphological types in 55 rich clusters of galaxies (1980ApJS...42..565D) Clusters, galaxy Galaxies, photometry V- and I- band CCD photometry of the central 0.18 square degree of Abell 168 was observed in November and December 1993 at the 1.05m Kiso Schmidt telescope (f/3.1). The CCD chip has 1000x1018 pixels, the pixel size is 0.752arcsec, giving a field of view of 12.0x12.7 arcmin. The total observed region was covered by 7 individual CCD fields. Note that some revisions were made by the author (TOMITA Akihiko) compared to the original publication.

ID Running number --- RAh Right Ascension 1950 (hours) number=1 The position accuracy is 5arcsec to 15arcsec depending on data quality. h RAm Right Ascension 1950 (minutes) number=1 The position accuracy is 5arcsec to 15arcsec depending on data quality. min RAs Right Ascension 1950 (seconds) number=1 The position accuracy is 5arcsec to 15arcsec depending on data quality. s DE- Declination 1950 (sign) number=1 The position accuracy is 5arcsec to 15arcsec depending on data quality. --- DEd Declination 1950 (degrees) number=1 The position accuracy is 5arcsec to 15arcsec depending on data quality. deg DEm Declination 1950 (minutes) number=1 The position accuracy is 5arcsec to 15arcsec depending on data quality. arcmin MajAxis Major axis diameter of the galaxy at 23 mag/arcsec2 isophote in I band arcsec Vmag V magnitude mag Imag I magnitude mag (V-I) color; it does not always coincide with (Vmag-Imag) because of round-off error. mag MType Eye inspected morphology number=2 category is either of E, S0, Se = early S [Sa-Sb], Sl = late S [Sc-Sd], I. If we can see any bar structure, we add `B'. --- Dressler Number given in Dressler =1980ApJS...42..565D --- HRV Heliocentric radial velocity taken from literature km/s Notes Various remarks, see number=3 We use the following abbreviations; LSB: low surface brightness; DBL: double system (the companion has the comparable size); COM: with a small companion (the number in parenthesis is the ID-number of the companion, if it is catalogued as another object in this list); comp: companion; dist: distortion; r: red; b: blue; sb: semi-blue; swb: somewhat blue. Note that No. 39 is the only IRAS source and No. 81 is the only radio source. -------------------------------------------------------------------------------- Remarks and Modifications: [TNT96] is used to designate the galaxies (ID column of table3) --- Francois Ochsenbein CDS 1996Apr12Akihiko Tomita <atomita@milano.mtk.nao.ac.jp> J_AJ_111_42.xml
