About GASPIC
The national observation services (SNO) GAlaxy Spectrophotometry, redshifts and physical parameters Publicly available In Cesam (GASPIC) results from the merger of the two SNOs GAZPAR and ASPIC. GASPIC is a AA – National Observation Action #5, Centres for data processing, archiving, and dissemination.
GAZPAR is a service giving access to astrophysical tools for the estimation of photometric redshifts, as well as physical parameters, from methods adjusting spectral energy distribution (SED) to multi-wavelength observed catalogues. The proposed tools are Le Phare, CIGALE, HyperZ, and Beagle and benefits from the expertise of associated astronomers.
You just have to upload your catalogues on a private and safe space and with the GAZPAR interface you define and configure the SED modelling tools you want to use (Le Phare, CIGALE, BEAGLE or HyperZ). You can then retrieve the package to execute the SED modelling tools on your computer and/or ask for our astronomers to process the request and provide you with the results, some quality tests and reports.
ASPIC is a portal dedicated to giving access to added values produced from several public spectroscopic or spectrophotometric surveys and is based on the data provision application (ANIS)
The expertise offered by ASPIC aims to address the whole measurement chain, including redshift measurements and reliability assessment, access to spectra and matched ancillary data like multi-band photometry via a dedicated information system.
