This function copies the information stored in a current region or period to a new region or period and generates a new id. It is useful when the user wishes to further subset a region (period) in multiple ways.
Examples
In this example, we first subset a swath with EOS_SW_DEFBOXREGION, duplicate the region creating a new region ID, regionID2, and then perform two different vertical subsets of these (identical) geographic subset regions:
regionID = EOS_SW_DEFBOXREGION(swathID, cornerlon, $
cornerlat, 0)
regionID2 = EOS_SW_DUPREGION(regionID)
regionID = EOS_SW_DEFVRTREGION(swathID, regionID, $
"Pressure", rangePres)
regionID2 = EOS_SW_DEFVRTREGION(swathID, regionID2, $
"Temperature", rangeTemp)
Syntax
Result = EOS_SW_DUPREGION(regionID)
Return Value
Returns new region or period ID or FAIL (–1) on error.
Arguments
regionID
Region or period id (long) returned by EOS_SW_DEFBOXREGION, EOS_SW_DEFTIMEPERIOD, or EOS_SW_DEFVRTREGION.
