CAGIRE: a wide-field NIR imager for the COLIBRI 1.3 meter robotic telescope

The use of high energy transients such as Gamma Ray Bursts (GRBs) as probes of the distant universe relies on the close collaboration between space and ground facilities. In this context, the Sino-French mission SVOM has been designed to combine a space and a ground segment and to make the most of their synergy. On the ground, the 1.3 meter robotic telescope COLIBRI, jointly developed by France and Mexico, will quickly point the sources detected by the space hard X-ray imager ECLAIRs, in order to detect and localise their visible/NIR counterpart and alert large telescopes in minutes. COLIBRI is equipped with two visible cameras, called DDRAGO-blue and DDRAGO-red, and an infrared camera, called CAGIRE, designed for the study of high redshift GRBs candidates. Being a low-noise NIR camera mounted at the focus of an alt-azimutal robotic telescope imposes specific requirements on CAGIRE. We describe here the main characteristics of the camera: its optical, mechanical and electronics architecture, the ALFA detector, and the operation of the camera on the telescope. The instrument description is completed by three sections presenting the calibration strategy, an image simulator incorporating known detector effects, and the automatic reduction software for the ramps acquired by the detector. This paper aims at providing an overview of the instrument before its installation on the telescope.Comment: Accepted by Experimental Astronom

Prise en charge des pathologies traumatiques des membres inférieurs et supérieurs à l’officine : guide de conseil sur la réalisation de bandages de type « strapping »

The making of a strapping consists of using an adhesive and elastic (or not) bandage to treat someone who’s suffering a trauma or to prevent it. Although using mainly by physiotherapists, the pharmacist can bandage someone in its pharmacy. However, he will never be able to make a diagnosis following a trauma, this task will be kept for a physician. Strapping can compress an injury, allowing to improve the removing of oedema and the healing process, while avoiding immobilization which is now known to be ineffective in recovery. This work consists to make accessible strapping techniques, and offer a booklet facilitating their making.Réaliser un strapping consiste à utiliser une bande adhésive et élastique (ou non) pour prendre en charge ou prévenir un traumatisme. Bien qu’utilisée principalement par le kinésithérapeute, le pharmacien pourra très bien réaliser des bandages dans son officine. Il ne devra par contre jamais réaliser un diagnostic suite à un traumatisme récent, ce rôle étant réservé au médecin. Le strapping va comprimer la blessure, ce qui permet d’améliorer l’évacuation de l’œdème, renforcer la cicatrisation, tout en évitant l’immobilisation qui est reconnue comme délétère à une bonne récupération aujourd’hui. Ce travail consiste à rendre les techniques de strapping plus accessibles et proposer un livret en facilitant la réalisation
