+  A FITS file inside of an ASDF file.
+description: |
+  This schema is useful for distributing ASDF files that can
+  automatically be converted to FITS files by specifying the exact
+  content of the resulting FITS file.
+
+  Not all kinds of data in FITS are directly representable in ASDF.
+  For example, applying an offset and scale to the data using the
+  `BZERO` and `BSCALE` keywords.  In these cases, it will not be
+  possible to store the data in the native format from FITS and also
+  be accessible in its proper form in the ASDF file.
+
+  Only image and binary table extensions are supported.

+description: |
+  A table is represented as a list of columns, where each entry is a
+  [column](https://asdf-standard.readthedocs.io/en/latest/generated/stsci.edu/asdf/table/column-1.1.0.html)
+  object, containing the data and some additional information.
+
+  The data itself may be stored inline as text, or in binary in either
+  row- or column-major order by use of the `strides` property on the
+  individual column arrays.
+
+  Each column in the table must have the same first (slowest moving)
+  dimension.
