The ASCII ECSV format supports doing round-tripping of meta data, and as of
version 1.3 that meta data can contain astropy objects like SkyCoord, Time,
Quantity and numpy arrays.

ECSV is formatted as comma or space-delimited, and there is currently no
built-in way in astropy to get round-trip meta-data support with
fixed_width_two_line.  Note that you can *write* your meta-data out in most
formats by serializing it into lines (by your favorite method), and then
set t.meta['comments'] = lines.
