This function reads data from the designated level fields into the data buffer from the subsetted time period.
Examples
In this example, we read data within the subsetted time period defined by EOS_PT_DEFTIMEPERIOD from the Time field:
periodID = EOS_PT_DEFTIMEPERIOD(pointID, 35208757.6d, $
35984639.2d)
IF (periodID NE -1) THEN BEGIN
status = EOS_PT_EXTRACTPERIOD(pointID, periodID, 1, $
"Time", buffer)
HDF_UNPACKDATA, buffer, dataTime, HDF_TYPE=[6]
ENDIF
Syntax
Result = EOS_PT_EXTRACTPERIOD(pointID, periodID, level, fieldlist, buffer)
Return Value
Returns SUCCEED (0) if successful and FAIL (–1) otherwise.
Arguments
pointID
Point id (long).
periodID
Period id (long) returned by EOS_PT_DEFTIMEPERIOD.
level
Point level (0-based long).
fieldlist
List of fields (string) to extract.
buffer
A named variable that will contain the data buffer. This buffer is in packed format. Use HDF_UNPACKDATA to convert it into variables.
