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 profileI(R)
atR=0
, which however produces an unphysical high central peak for some choices ofdR
anddxy
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 inRmin < R < dxy/2
and dividing by the areapi[(dxy/2)**2-dR**2]
. reduce_chi2
now does not modify the input visibilities
