  A new method Spherical Rectangular Equal-Area Grid (SREAG) was proposed in
Malkin (2019) for splitting spherical surface into equal-area rectangular
cells. In this work, some more detailed features of SREAG are presented. The
maximum number of rings that can be achieved with SREAG for coding with 32-bit
integer is $N_{ring}$=41068, which corresponds to the finest resolution of
$\sim$16$''$. Computational precision of the SREAG is tested. The worst level
of precision is $7\cdot10^{-12}$ for large $N_{ring}$. Simple expressions were
derived to calculate the number of rings for the desired number of cells and
for the required resolution.
