Spectroscopic surveys in astrophysics and cosmology require an accurate knowledge of the non-uniformity in the transmission of light introduced by the telescope optics, which yields a non-uniform response all over the focal plane. In this work, we report a preliminary study on the in-flight flux self-calibration procedure and we characterize...

We present a method for the in-flight relative flux self-calibration of a spectro-photometer instrument, general enough to be applied to any upcoming galaxy survey on satellite. The instrument response function, that accounts for a smooth continuous variation due to telescope optics, on top of a discontinuous effect due to the segmentation of...

We developed a front-end electronic system for large area photomultipliers. Connection to the PMT can be made by a single cable, useful to minimize cabling in a underwater detector. The cabling is done in the rear part of the crate to permit easy access to the electronic boards. A front-end board houses 8 channels each one is composed by a...
