Herschel data products systematically generated by the SPG pipeline are made available to the users through the Herschel Science Archive (HSA) immediately after the pipeline processing is completed, typically 1-2 days after an observation has been executed. Following the completion of some basic quality control checks, something which may take from a few additional days to weeks, depending on the circumstances, notification e-mails are sent to the data owners that can then be informed about any quality issue affecting their observations.

By using the HSA User Interface, astronomers can search, browse, select and retrieve Herschel data products according to the observations proprietary rights as explained in Chapter 1 of the Herschel Data Analysis Guide.

Access to the HSA User Interface is provided from the following link:

For every Herschel observation, the data populating the HSA consist of the observational products generated by the pipeline, containing the scientific data, together with the calibration and auxiliary products as described in the Herschel Data Products section. In addition, associated quality information, generated to support archive users in the assessment of their scientific products, is also included.

The HSA provides data products as FITS format files at different levels of data reduction which can be used for further processing within the Herschel Interactive Processing Environment (HIPE), or with any other standard data processing package. It will also host highly processed data returned from the observers at a later stage in the mission.
