Hi, In IRIS, when you want to do verification you can't ungray a few items
 
1. Select the Verification tab at the bottom
2. Select Map Data
3. The following 3 items are grayed out, and you can't turn them off:
  MRMS Base Reflectivity
  MRMS Composite Reflectivity
  MRMS Echo Tops
 
So the reflectivity image always shows when I am doing verification,
  especially in real time.
 
Is there anyway from those items to be ungrayed so you can turn them
  off if you like?
 
I try to send an image too.
 
Thanks,
Jim
