Abstract

The final limits of the photometric precision that may be achieved with a robotic telescope will depend upon the detection and control of all possible error sources. This involves efforts in mainly three related domains: instrumentation technology, calibration and data treatment. Here we will focus on the optimization of procedures for the automatic reduction of data taken with the 50-cm robotic telescope that is remotely operated at Centro de Astrobiolog´ıa. The adopted strategies and the photometric precision achieved at different stages of the development of the project will be discussed, highlighting some of the main factors involved in past and future improvements.
