title: Combining Astropy FITS files?
body: <p>So I have some Astropy fits tables that I save (they have all have the same format, column names, etc.). I want to take all these fits files and combine them to make one large fits file.</p>
  
  <p>Currently, I am playing around with the astropy.io append and update functions to no avail.</p>
  
  <p>Any help would be greatly appreciated. </p>
