"# Summary of AGIPD dark characterization #\n",
"\n",
"The following report shows a set of dark images taken with the AGIPD detector to deduce detector offsets, noise, bad-pixel maps and thresholding. All four types of constants are evaluated per-pixel and per-memory cell.\n",
"\n",

"**The offset** ($O$) is defined as the median ($M$) of the dark signal ($Ds$) over trains ($t$) for a given pixel ($x,y$) and memory cell ($c$). \n",
"\n",
"**The noise** $N$ is the standard deviation $\\sigma$ of the dark signal.\n",
"\n",
"$$ O_{x,y,c} = M(Ds)_{t} ,\\,\\,\\,\\,\\,\\, N_{x,y,c} = \\sigma(Ds)_{t}$$\n",
