The Reionization and Transients InfraRed camera (RATIR) is a simultaneous optical/NIR multi-band imaging which 100% time-dedicated to the followup of Gamma-ray Bursts. mounted on 1.5-meter Johnson telescope Mexican Observatorio Astronomico Nacional Sierra San Pedro Martir in Baja California. With rapid slew capability autonomous interrupt capabilities, system will image GRBs 6 bands (i, r, Z, Y, J, H) within minutes receiving satellite position, detecting optically faint afterglows NIR...
The Reionization And Transients Infra-Red (RATIR) camera is intended for robotic operation on the 1.5-meter Harold Johnson telescope of Observatorio Astronómico Nacional Sierra de San Pedro Mártir, Baja California, Mexico. This paper describes work we have carried out to successfully automate and prepare it RATIR. One novelty our use real-time absolute astrometry from finder telescopes point guide main telescope.
We present an overview of the development end-to-end simulations programs developed for COLIBRI (Catching OpticaL and Infrared BRIght), a 1.3m robotic follow-up telescope forthcoming SVOM (Space Variable Object Monitor) mission dedicated to detection study gamma-ray bursts (GRBs). The contains description Exposure Time Calculator, Image Simulator photometric redshift code in order assess performance COLIBRI. They are open source Python packages were be easily adaptable any optical/...
We conducted an 18 month long study of the weather conditions Vallecitos, a proposed site in México to harbor northern array Cherenkov Telescope Array (CTA). It is located Sierra de San Pedro Mártir (SPM) few kilometers away from Observatorio Astronómico Nacional. The based on data collected by ATMOSCOPE, multi-sensor instrument measuring and sky conditions, which was commissioned built CTA Consortium. Additionally, we compare optical observatory at SPM Vallecitos regarding temperature,...
COLIBRI is one of the two robotic ground follow-up telescopes for SVOM (Space Variable Object Monitor) mission dedicated to study gamma-ray bursts, allowing determination precise celestial coordinates detected bursts. telescope a two-mirror Ritchey-Chrétien whose concave primary and convex secondary mirrors have diameters 1325mm 485mm respectively. The are currently manufactured at LAM (Laboratoire d'Astrophysique de Marseille). In this article, advancement work presented. We also give...
We present the results of a modification performed in optical system 62 cm telescope (f/14.32) at observatory “Severo Diaz Galindo” Universidad de Guadalajara, Mexico. This consists change distance between the primary and secondary mirrors from 1020 to 1135 mm. With this, image plane 5200 mm 600 mm, measured vertex mirror, is obtained. The latter allow get first astronomical images of The Telescope. was necessary because alignment errors, such as between and secondary original were...
We present the results of optical characterization mirrors telescope 62cm observatory "SEVERO DIAZ GALINDO" property University Guadalajara. use Ronchi test and a spherometer to measure by first time, radius curvature for primary secondary mirror, parameters system were obtained using commercial software ZEMAX. confirm that both are adequate work in configuration do astronomy.
While testing a Stromgren spectrophotometer attached to the 1.5-m telescope at San Pedro Martir observatory, Mexico, number of A-type stars were observed, one which, HD 207331, presented clear indications photometric variability. CCD data acquired soon after, confirmed its In order determine pulsation behaviour more accurately, uvby differential photoelectric photometry was carried out for three nights. As result period analysis light curves we have found dominant mode 21.1 c/d with an...
