I am new to astronomy and I was given the task of finding out if there are objects which can't be resolved by a telescope of resolution 5 arcseconds.
I was given the values of RA and Dec of these objects in degrees.
RA DEC 201.1999388 27.49294258 201.2048319 27.49212959 201.1984702 27.4978016 201.2025157 27.51610266 201.1997827 27.51743447 ...etc
How can I find these in the simplest way? Is there any simple formula which can be used to achieve this which is computationally efficient as well?
