=item Isophotal_flux, Total_flux, Core_flux, Core1_flux, Core2_flux,
 Core3_flux, Core4_flux, Core5_flux - C<Astro::Flux> objects pushed into
 the C<Astro::Catalog::Item> fluxes accessor.

RA and Dec are assumed to be in J2000 coordinates, and are in units
of radians. The isophotal flux is assumed to be in units of counts,
and is converted into a magnitude through the formula -2.5 * log10(flux).
The position angle is assumed to be the angle measured counter-
clockwise from the positive x axis, in degrees.

An attempt to read in the DATE-OBS header is made so that flux measurements
can be timestamped. If the DATE-OBS header does not exist, then the current
date and time will be used for the flux timestamps.

There are optional named parameters. These are case-sensitive, and are:
