HELP project - a dreamed-of multiwavelength dataset for SED fitting: the influence of used models for the main physical properties of galaxies.

The Herschel Extragalactic Legacy Project ( HELP) focuses to publish an astronomical multiwavelength catalogue of millions of objects over 1300~deg$^2$ of the Herschel Space Observatorysurvey fields. Millions of galaxies with ultraviolet-- far infraredphotometry {make} HELPa perfect sample for testing spectral energy distribution fitting models, and to prepare tools for next-generation data. In the frame of HELPcollaboration we estimated the main physical properties of all galaxies from the HELPdatabase and we checked a new procedure to select peculiar galaxiesfrom large galaxy sample and we investigated the influence of used modules for stellar massestimation.
