This function reads data from the designated level fields into the data buffer from the subsetted time period.
Result = EOS_PT_EXTRACTPERIOD(pointID, periodID, level, fieldlist, buffer)
Returns SUCCEED (0) if successful and FAIL (–1) otherwise.
Point id (long).
Period id (long) returned by EOS_PT_DEFTIMEPERIOD.
Point level (0-based long).
List of fields (string) to extract.
A named variable that will contain the data buffer. This buffer is in packed format. Use HDF_UNPACKDATA to convert it into variables.
None
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
