Details:
I found some catalogues (fits tables) that instead one value per each column
and row, they are arrays. As a particular example it can be checked the
catalogue of DECaLS around NGC1035 (link:
https://portal.nersc.gov/project/cosmo/data/legacysurvey/dr8/south/tractor/039/tractor-0397m080.fits).
In this catalogue there are multiple columns, but just focusing on the one
with name `apflux_g' it can be seen that there are multiple values for a
single object (row). They correspond to photometry measurements on different
apertures. When considering this table with the program `Table', it gives as
an output a no-sense result.
Consider the column `apflux_g' and the last row, with `asttable':
asttable tractor-0397m080.fits -capflux_g
the result is:
0.274843
It is a single value. However, the real value is an array (read with
`topcat'):
(0.15832691, 0.33208665, 0.523447, 0.87126434, 1.099582, 1.4097637, 1.3801724,
1.514054)
