Comments on "A Comparison of Different Analytical Methods of Determining the Solid Angle of a Circular Coaxial Source-detector System"

This paper gives some critical remarks on a recent publication concerning analytical methods to calculate the solid angle subtended by a disk-shaped detector for a coaxial, homogeneous, disk-shaped source (Galiano and Rodrigues, 2006). The mentioned paper lacks rigour and contains numerous incorrect statements, including mistakes in the mathematical expressions of the eight equations that are being scrutinised, as well as computational errors. The conclusions of the paper are incorrect and bear little scientific relevancy. In particular, the authors are wrong concerning the alleged ‘unphysical results’ obtained from Pommé’s series expansion of Ruby’s formula (Pommé, 2004). Some of the paper’s shortcomings are briefly discussed.
