This topic is covered in detail in SDRG Section 4.1
Herschel data are stored in ESA's Herschel Science Archive (HSA):
There are three main ways to import data from the HSA into HIPE:
myobs=getObservation(obsID, useHsa=True)
, or to directly save the data to disk myobs=getObservation(obsID, useHsa=True, save=True)
.
myObs=getObservation(path="/path/to/dir")
.
saveObservation(myobs, poolName="myPool", saveCalTree=True)
.
Once the data are saved (and indexed) on your hard disk, the Observation Context can be read back into HIPE using, myobs=getObservation(ObsID)
.
This topic is covered in general in SDRG Section 4.2
For Photometer modes see SDRG Section 6.1, and for the Spectrometer see SDRG Section 7.2
Once the data are in HIPE, the Observation Context will be visible in the HIPE variables window:
Double click to open the ''Observation Viewer'' (or right click > Open With>Observation Viewer)
Data are available at different levels of processing (SDRG Figure 4.11):
Level 0: Raw data
Level 0.5: Basic processed voltage timeline data
Level 1 (Photometer): Flux calibrated timelines in Jy/beam
Level 1 (Spectrometer): Interferograms in V
Level 2 (Photometer): Flux calibrated maps for signal, error and coverage in Jy/beam
Level 2 (Photometer): Flux calibrated maps for signal, error and coverage in MJy/sr
Level 2 (Photometer): For SSO observations, point source maps in the moving frame for signal, error and coverage in Jy/beam
Level 2 (Photometer): Destriper Diagnotic Products
Level 2 (Spectrometer): Extended calibrated spectrum in W/m2/Hz/sr and point source calibrated spectrum in Jy; or 2D list of spectra and spectral cube in W/m2/Hz/sr
Other ancillary files are also available (see SDRG Section 4.2.5)
Data products can be viewed by clicking on the small “+” next to the folders to expand the tree in the same way as a file system. Clicking on one level opens it in an appropriate viewer (right click to choose which). Double clicking opens the viewer in its own tab. The main viewers are:
Context Viewer – shows the entire context as a tree of products
Dataset Viewer – shows data as a table array
TablePlotter – allows one table of data to be plotted
OverPlotter – allows different tables to be opened in the same plotter
Image Viewer – displays a 2D image
SDI/SDS Explorer – shows interferograms/spectra from all Spectrometer detectors
