... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... First, there is a set of residual plots against airmass for each night. ... If you reply ``YES'', it will show you some plots intended to help you distinguish between time-dependent extinction and time-dependent zero-point drift. ... Figure: Sample drift plot . The principle behind these plots is that time-dependent extinction produces errors (and hence, we hope, residuals) that are proportional to airmass; but instrumental drift produces residuals uncorrelated with airmass. ...
