Hi Everyone,

I've been having trouble working out what the rms and theoretical rms values mean from uvplt and uvstat. In short I have some snap shot data which has a noise level (as determined from imaging or the original integration time estimates) of about 1mJy. When I output and plot things like amplitude or real component values for the visibilities they have a scatter between them consistent with this i.e. a few mJy. However if I output the rms for these same visibilities from either uvplt or uvstat and either theoretical or empirical estimates I get values in the 100s of mJy. This cant be the rms expected in the amplitudes because the scatter is 100 times smaller so I'd like to know what these values mean?

Thanks

Mike
