Shapes are not measured for bright lines

I took a look at the calculated moments from 96925 r1. I take it that xx is the xx adaptive moment (it'd be better if we called it something like Ixx).
The fluxes look OK as do the moments , but

np.sum(np.isfinite(als.xx)), np.sum(np.isfinite(als.flux)), np.sum(np.isfinite(als.xx[als.flux > 25])) == (22204, 102735, 0)

so none of the bright lines have measured moments.
