Description
Statistic mode in the single dish plotter raises an error in an occation, i.e., (1) specunit is set to one other than 'channel' and (2) a selected region to calculate statistics doesn't overwrap spectral range of IF0. This is a bug in asap plotter.

I forgot to close this ticket.
After a while, I tested numpy.median(MaskedArray?) again but could not reporduce NaN anymore.

ASAP plotter prints statistics (max/min/median/mean/sum/stddev) of spectra only in a selected subplot. The previous behavior was printing stats of all spectra in scantable, which caused the error.
The stats are calculated based on numpy functions, and I found numpy.median(MaskedArray) often returns NaN as a result. Need more investigations.
