Notes. 

(*)

In the astrometric system embedded into the F606W drizzled fits image.

(a)

From the isochrone fit of Fig. 9 (See Sect. 5).

(b)

Projected distance from the center of VV124.

(c)

From aperture photometry on concentric annuli, assuming a limiting radius rl = 2.0″.

(d)

From aperture photometry with radius r = 2.0″.

(e)

Assuming (M/L)V = 0.061 from the BASTI database, for a model having Age = 30 Myr, Z = 0.004 and a Kroupa IMF.
