Notes. (a)Npix: total number of valid spatial pixels in the field. (b)μ, σ: mean value and standard deviation from Gaussian fit to the peak of the rms histogram, respectively. (c)rms min, max: minimum and maximum rms, respectively. (d)Median, mean, stddev: median, mean and standard deviation including all rms values, respectively.
