[netCDFJava #CZW-502913]: combining satellite bands via ncml



This ssec user asked a few questions of the thredds group, but the one 
about data readout and middle mouse buttons might be more for the IDV team.

New Client Reply: combining satellite bands via ncml

Hi,

When the middle mouse button is pressed in either IDV or McIDAS-V a data 
readout is displayed.  In the case of this aggregated file, no value is shown 
for the aggregated data.
