The 2MASS Extended Source Catalog (XSC) will include all resolved galaxies, regardless of their size, but will not accurately record the integrated flux for the largest galaxies due to their proximity to a "scan" edge. A typical 2MASS survey scan is 8.5 arcmin * 6 degrees, with 10% over...

but background polarisation must be estimated within ~1 arcmin from the source to avoid instrument polarisation that becomes significant at the edge of the field of view69. The reduced Stokes parameters are reported adopting as a reference direction the perpendicular to the great circle passing...
PA error was similar all night, between 19 and 23 arcmins. If you run the PHD2 Guide Assistant after Cal it will advise on the Min Mo settings for the Seeing, and give an accurate measure of the PA, as iPolar doesn't seem to be working for you. ...
The CC is a photometric and astrometric survey with the center at (alpha ,delta )_J2000=(35136, 3436arcmin ) and radius of 10 degrees. The CC is based on recently published astronomical catalogues, e.g. Hipparcos and Tycho-2, and supplemented by relevant astrophysical data from numerous ...
The open cluster Stephenson 2 is one of the most massive open clusters in the Milky Way. It was first noticed by American astronomer Charles Bruce Stephenson, whoreportedthe discovery of “ten faint, dust-reddened stars, several of them probable M supergiants, in a 1.5 x 3 arcmin area of...
