6.7.2 Examples for imstat

The following are some examples using the B1608+656 Tutorial

http://casa.nrao.edu/Doc/Scripts/b1608_demo.py

as an example.

To extract statistics for the final image:

   xstat = imstat(’b1608.demo.clean2.image’)
# Printing out some of these
   print ’Max   = ’+str(xstat[’max’][0])
   print ’Sigma = ’+str(xstat[’sigma’][0])
# results:
# Max   = 0.016796965152
# Sigma = 0.00033631979385

In a box around the brightest component:

   xstat_A = imstat(’b1608.demo.clean2.image’,box=’124,125,132,133’)
# Printing out some of these
   print ’Comp A Max Flux = ’+str(xstat_A[’max’][0])
   print ’Comp A Max X,Y  = (’+str(xstat_A[’maxpos’][0])+’,’+str(xstat_A[’maxpos’][1])+’)’
# results:
# Comp A Max Flux = 0.016796965152
# Comp A Max X,Y  = (128,129)
