To establish the SAMP connection between HSA and HIPE follow the steps given in the attached video: 1. Open the HSA Interface [http://archives.esac.esa.int/hsa/whsa] 2. Open the SAMP Hub 3. Open HIPE 4. Send data from HSA to HIPE Note that HIPE a...
To find out about the steps to follow in reducing SPIRE spectroscopy and, in particular, how to carry background subtraction of spectra, there is a Herschel Science Centre short videotutorial that shows you the steps involved and also describes the data p...
As for SPIRE FTS spectroscopy, semi-extended sources provide the user with a very special set of problems, as they are sources of a size intermediate between point sources (i.e. unresolved) and extended sources (clearly resolved), for which neither point ...
Extended sources provide the user with a particular set of problems that require special techniques. We assume that you have watched the Herschel Science Centre short videotutorial called _Starting with PACS Spectroscopy_: https://www.youtube.com/watch...

HIFI spectra can be of two kinds: ON source spectra, in which the keyword "isLine=True) and OFF source, reference position spectra, for which isLine=FALSE. The reference position though may, itself, be contaminated by background emission, compromising the...
Both point source photometry - from source fitting - and aperture photometry can be extracted from SPIRE maps. If you prefer to obtain aperture photometry from SPIRE maps, you should check the appropriate Herschel Science Centre short videotutorial for ...
The Herschel Science Centre has produced a useful short videotutorial that shows you how to use a useful script in HIPE for SPIRE line fiiting (NB: it does not cover the fully interactive mode of line-fitting). You can find the short videotutorial here: ...
We have prepared a short videotutorial on Inspecting Data Products in HIPE. This will explain to you the different types of data products that you can find and their content and applicability. You can find it here: https://www.youtube.com/watch?v=Y7LJK0m...
The HIFI Observation Context consists of six categories of products that are found in the Herschel Science Archive (data at various levels of processing, browse products. calibration products, auxiliary products, quality products and trend analysis produc...
The Herschel Science Centre has produced a short videotutorial guide for users of SPIRE spectrometry data to show how to use the observation context and where to find it. https://www.youtube.com/watch?v=D66Yxz8waVI&t=413s [https://www.youtube.com/watch?...
If you are an absolutely beginner with Herschel data and want to learn how to do photometry on PACS observations there are two places to start before working with data. First, you should look at the Quick Start Guide for Photometry (CSG), otherwise known...
There are two excellent starting points for learning how to use PACS spectroscopy data. We recommend strongly that you start by reading the Quick Start Guide to Spectroscopy [https://www.cosmos.esa.int/documents/12133/996891/PACS+Data+Reduction+Launchpad+...
The Herschel Science Archive (HSA) allows multiple categories of searches to be carried out using different criteria. In particular: * Search by target name. * Search by coordinates (in a radius around a particular position). * Search by catalogue ...

  Name searches in the HSA only work by cross-referencing with either the SIMBAD database of (mainly) stellar objects or the NED database of extragalactic objects that both, logically, exclude Solar System Objects. These must be identified using their N...
Answer supplied by Eva Verdugo: The Herschel Science Archive [http://archives.esac.esa.int/hsa/whsa] includes in the "Basic Search" panel a field called "Access Status" that allows searching by "Public", or by "Restricted" observations. Some observation...
We have prepared a short videotutorial to explain to users how to use the Herschel Science Archive User Interface. You can find it here: http://youtu.be/IgGNpUgubkw [http://youtu.be/IgGNpUgubkw]

Ancillary Data Products (ADPs) are data products that correspond to an instrument or too the observatory rather than to a single science observation. These include a wide variety of engineering and diagnostic data. The Herschel Science Centre has produced...
Highly processed data products are sets of data that have been reduced by experts working for the Herschel Science Centre because they have issues that makes them extremely difficult to reduce optimally by automatic pipeline, or even by a non-expert in in...
The Herschel Science Archive (HSA) provides a large amount of information in response to a search for observations of a particular target. In particular: * How many observations there are in the HSA for this target, their status and quality. * What p...
