The development of the method has been greatly assisted by photography, while the application of photometric measurements has been a powerful auxiliary in the work.
Photometric catalogues, accordingly, form an indispensable part of stellar statistics; and their construction has been zealously prosecuted.
Kempf with a polarizing photometer; but by far the most comprehensive work of the kind is the Harvard Photometric Durchmusterung (1901-1903), embracing all stars to 7.5 magnitude, and extended to the southern pole by measurements executed at Arequipa.
Thus, the photometric data in this table are not strictly homogeneous, and should be considered to be approximate values only.
We estimate a photometric redshift of for this galaxy, using the methods of Mobasher et al.
