Hi, Recently, I found the multipole moment calculations in QuasiLocalMeasures show large errors, e.g. 20% for the second mass moment of my project.
The error exists even in the test data of the thorn but it's around a few percent. But it couldn't be improved even with increased resolution. From a rough investigation, I found this is because the one in coordinate construction which was supposed to be equal to cos(theta) for a stationary black hole deviates a bit, making erroneous value. I didn't go further. I'd like to know your opinion or any experiences on this. Cheers, Hee Il p.s. I haven't checked whether there's an update of the thorn in the latest version of ET.
