Disc Mass
Hi,
I have a disc with
Radii 1024
{
Min 0.3
Max 3.3
Spacing ARITHMETIC
}
Sectors 3000
Layers 1
...
Density
{
Slope 1
Minimum 1.e-20
Start 0.0001
}
I thought the mass of the disc would be m_{\mathrm{disc}}=2\pi\int_{0.3}^{3.3} 0.0001 r^{-1} dr = 0.00150664
(in code units) but in the output I see Disk total Mass : 0.00188127
. It's the same order of magnitude, but I wonder why I'm getting a different number?
Maybe I'm making some stupid mistake...
