HIPS for spectroscopic observations

Durand Daniel, Fernique Pierre, Boch Thomas

We are all well aware of the success of the Hierarchical Progressive Surveys (HiPS) if for images surveys and catalogues. We are proposing to extend the HIPS usability to spectra data. Spectrum are neither points (suitable for catalogue) and neither images. Since every spectrum represents an aperture on the sky from from which the light is spread over ta defined wavelength coverage, it should possible to represent as HIPS tiles the actual aperture used on the sky and use the HIPS metadata extraction to expose the wavelength coverage. The advantages of using HIPS in addition to MOC are the link to all input spectra as well as giving the user an indication of the number of input for each HIPS pixel. Although not available yet, we propose a way to search and filter the HIPS entries based on a user selected filter on the metadata to be able to search and select on the wavelength axis.
