Why the distribution of logsigma can not cross zero? #18

Open Zijian-astro opened 1 week ago

I just find that the distribution of logsigma estimated from cont.do_mcmc can not cross zero. For example, when I run one simulated lc and get a logsigma distribution estimation as this fig:

this look normal, and I expect that when I replace a simulated lc with smaller sigma, the logsigma distribution estimation will globally shift to the left. But in fact I got a fig as follows:

so it seems that the estimation distribution of logsimga can not cross 0, I think this is counterintuitive and I don't why.

Looking forward to your reply. Many thanks.
