Descripción
Data reduction procedures aim to minimize the impact of data acquisition
imperfections on the measurement of data properties with a scientific
meaning for the astronomer. To achieve this purpose, appropriate
arithmetical manipulations with data and calibration frames must be
performed. Furthermore, a full understanding of all the possible
measurements relies on the firm constraint of their associated errors.
We discuss different strategies for obtaining realistic determinations
of final random errors. In particular, we highlight the benefits of
considering the data reduction process as the full characterization of
the raw data frames, but avoiding, as far as possible, the arithmetical
manipulation of the data until the final measurement and analysis of the
image properties. This approach will be used in the pipeline data
reduction for ELMER and EMIR.
