Beginning of ReadMe : J/other/AstBu/70.24 Updated 2MFGC catalog (Mitronova+, 2015) ================================================================================ Visual survey of 18020 objects from the 2MFGC catalog. Mitronova S.N., Korotkova G.G. <Astrophys. Bull., 70, 24 (2015)> =2015AstBu..70...24M ================================================================================ ADC_Keywords: Galaxies, IR ; Galaxy catalogs ; Infrared sources ; Photometry, infrared ; Morphology Keywords: galaxies: spiral - catalogs - surveys Abstract: We spent a solid overview of the infrared and visual images 18020 2MFGC galaxies selected in the automatic mode of 1.64 million. Extended objects XSC-2MASS catalog with respect infrared axes, a/b>=3. This work is aimed at excluding "spurious" objects from the list of flattened galaxies. Browse more than 80000 images in different filters were able to identify 1512 (8.4% of the total) of such objects. Found duplicate in 2MASS measurements of 23 galaxies with, respectively, two rooms 2MFGC, and 3 flat galaxy, not accounted for in other directories and in close proximity with the three "spurious" galaxies. The main part of the excluded facilities accounted for magnitudes less Ks=13mag. They are characterized by small angular size, low surface brightness and the concentration index. Exception objects identified significantly reduced the spread of values in the two-dimensional distribution. Results of work in the form of notes will be placed in the astronomical database VizieR, NED, HYPERLEDA.
