Figure supporting an in-class exercise, carried out during the lab period. The students were asked to answer the following questions:
\begin{itshape}
Consider the attached image of a nova observed with the millimeter telescope CARMA at
96 GHz (Panel A). Histograms of pixel values are shown in Panels B and C (Panel C is
just a zoom-in of a region on Panel B); these are just like the histograms you made in DS9's \verb|Scale Parameters|. The pixel values after calibration are
...
$\sigma$ significant---that is, if the detected source is at least five times brighter than the
standard deviation of the background. In other words, the source's peak flux should be $S_{\rm max} > (\bar{S} + 5 \sigma$). Estimate how many sigma the peak flux density
of the nova is, and show your reasoning. Would this detection be taken seriously by
other astronomers?
