This function uses the CASA imstat task to compute the rms and standard deviation of chunks of a CASA image cube, and plots the result vs. the width of the chunk (in channel space).


tt.imstatCube(img, box, startchan=None, maxwidth=None, minwidth=2,
               plotfile='', mJy=True, plotrange=[0,0,0,0], mark11=None)
  • img: CASA image cube to analyze
  • box: 'x0,y0,x1,y1'
  • startchan: center of range of channels to analyze
  • minwidth: narrowest group of channels to analyze
  • maxwidth: widest group of channels to analyze
  • mjy: if True, then scale the statistical values up by 1000 (from Jy/beam to mJy/beam)
