opening images with ds9 from a python script

I did it the old-fashioned way (os.system is going to be deprecated):

  import os

  os.system("~/ds9  -zoom 0.3 -scale mode 99.5 -file "+ 

GalaxyParameters.getSDSSUrl(listFile, dataDir, i) +" -file  "+ 

GalaxyParameters.getMaskUrl(listFile, dataDir, simpleFile, i) +" -match frames")
