2 years ago I pushed a fix in https://github.com/moustakas/legacyhalos/commit/877f6ecd6d140ba0cf53ff096cd2a9f90e04280a although I'm still getting some warnings. At least now, however, the unit is written to the header (whereas it was dropped before).

If this is meant to be a custom unit, define it with 'u.def_unit'. To have it recognized inside a file reader or other code, enable it with 'u.add_enabled_units'.

Writing out the ellipse files raises the warning reported in https://github.com/desihub/fastspecfit/issues/72. The fix is to pass a custom string unit, 'nanomaggies'.
