mtazzari/galario: 1.0.3

Bugfixes:

• corrects a bug in the computation of the central pixel brightness when creating the 2D image from a 1D profile. For versions <=1.0.2 the central pixel brightness (in Jy/px) was computed by extrapolating the input brightness profile I(R) at R=0, which however produces an unphysical high central peak for some choices of dR and dxy and for very steep functions (e.g. power laws). With the 1.0.3 release, the central pixel is computed as the average flux arising from the central pixel by integrating the brightness produced in Rmin < R < dxy/2 and dividing by the area pi[(dxy/2)**2-dR**2].
• reduce_chi2 now does not modify the input visibilities
