First Light with RATIR: An Automated 6-band Optical/NIR Imaging Camera

摘要

The Reionization and Transients InfraRed camera (RATIR) is a simultaneous optical/NIR multi-band imagingcamera which is 100% time-dedicated to the followup of Gamma-ray Bursts. The camera is mounted on the1.5-meter Johnson telescope of the Mexican Observatorio Astronomico Nacional on Sierra San Pedro Martir inBaja California. With rapid slew capability and autonomous interrupt capabilities, the system will image GRBsin 6 bands (i, r, Z, Y, J, and H) within minutes of receiving a satellite position, detecting optically faint afterglowsin the NIR and quickly alerting the community to potential GRBs at high redshift (z&6-10). We report hereon this Spring's first light observing campaign with RATIR. We summarize the instrumental characteristics,capabilities, and observing modes.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
