This function reads data from the designated level fields into the data buffer from the subsetted time period.
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, $
IF (periodID NE -1) THEN BEGIN
status = EOS_PT_EXTRACTPERIOD(pointID, periodID, 1, $
HDF_UNPACKDATA, buffer, dataTime, HDF_TYPE=
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.
