On the Web interface, you will find the Science Files Requested box on
the HST Retrieval Configuration Options screen. The use may choose the "Calibrated"
and/or "Uncalibrated options. Either set of data will be produced by OTFR and
you will be shipped only the files you asked for.
On Starview, make the request as you normally would. On the Retrieval
Request - File Options screen, you will find a check box for Calibrated data.
More detailed information about each dataset is found by going to the HST
Instrument Searches screen from the Starview Search Menu. From there,
select on the OTFR menu option for the appropriate instrument search.
The OTFR screen contains some fields that are useful for determining
if your data need reprocessing. The date of last software change is the most
recent date of installation of new calibration software which will likely
have a significant impact on the results of calibration. The date of last
action update is the date of the last change of parameters for the dataset
that could affect the results of calibration. You can use this information
to determine whether there is any benefit in re-requesting a dataset from
OTFR. If the dataset you have already obtained from OTFR was processed after
both dates, then there is likely to be no significant advantage in
requesting the dataset again.
If you have requested only calibrated data and the chosen dataset
is not supposed to be calibrated, then no files are returned with a normal complete status.
If the data was supposed to be calibrated but fails to process, operations staff will
work to diagnose the problem if possible and talk with you about the problem.
If you have checked uncalibrated data, you will receive the uncalibrated data.
