A blog of my work as a PhD student
Today I spent time rounding off the different special cases for quads and triples. Special cases being: cosmic scatter=0, cosmic scatter=10 000kpc. I did these for pairs, here is an update version of the contour plot: The underlying problem here being the ones that match the model best are at Read more…
Insofar, i’ve been testing the TC08 model as if there is cosmic scatter of 0.25dex at EVERY LOS that’s simualted. This was a result we found in a previous test of the TC08 model. While we took measures to stop ridiculous scatter at very small separations, it’s important to test Read more…
I needed to check, just like i did for triples, whether each LOS in the quad had 900 matches or 0. 900 meaning that it was a LOS that could be matched to, and 0 meaning it was simply an upper limit. After doing the same test, it seems that Read more…
If the cosmic scatter in my model is zero, then I am essentially following the TC08 model exactly. There is no upper or lower envelope of EW values for a given mass profile of the halo. Just one curve. cov_frac:0.0100000 ell_c: 1.00000 Significance:1.4538320e-19 D:0.94777800 cov_frac:0.100000 ell_c: 1.00000 Significance:1.1752003e-15 D:0.85333300 cov_frac:0.200000 Read more…
