The Secondary Standards Programme for OmegaCAM

TL;DR: In this paper, the authors present a preliminary catalog for the OmegaCAM wide-field imager, which will be used to bootstrap the construction of the secondary standards catalog for 8 Landolt equatorial fields during the first year of operation.

Euclid preparation: XXIII. Derivation of galaxy physical properties with deep machine learning using mock fluxes and H-band images

Euclid Collaboration L. Bisigello, +197 more
TL;DR: Deep Learning Neural Networks and Convolutional Neutral Networks perform well in measuring the properties of these galaxies and have an accuracy which is better than traditional methods based on spectral energy distribution, but it is found that the estimates of stellar masses improve with the use of an image, but those of redshift and star-formation rates do not.

Design and measured performance of the ISO Short Wavelength Spectrometer

TL;DR: The Short Wavelength Spectrometer (SWS) is one of the four instruments for the Infrared Space Observatory (IROSO) as discussed by the authors, which operates at about 3 K employing diffraction gratings, if offers a resolving power between 1000 and 2000 in the wavelength range 245 to 45 micrometers.
