Sample Galaxies

These galaxies are all taken from Brent-9060 HI catalog, when cross-matching with other catalogs.

A few galaxies to work with.

• WISE Cosmic Flow catalog (photometry of a sample of SDSS galaxies (261 galaxies), by Don and Mark): ​http://www.ifa.hawaii.edu/~ehsan/html_tables/all_wise.html
• First Look (comparsion with Hall et al. 2012) first_look
• Hall 2012 (SDSS Catalog): hall_sdss
  SDSS Imaging Data: M. Hall et al. 2012, MNRAS,425,2741

This is the my photometry compared with that of Don and Mark ... We are both using SDSS data and GLGA pipeline ...

• (see below for the table)

One of the most deviant points belongs to PGC-39241 ... Looking at the below figure, the difference in masking and taking care of cosmetic can be the source of deviation. Also it's been observed that for the cases with high degree of masking within the red totted aperture, the sensitivity to the Position Angle of the ellipse increases, since the pixel value of the masked regions is estimated using the isophots.
