Calibration

Some of the variables are stored as integers for saving disk space. For each variable, the user will find 2 standard SDS attributes called « scale_factor » and « add_offset ». Most of time, the standard HDF formula for scaling raw file values to physical ones is used :

science_value = ( raw_value – add_offset ) * scale_factor

Nevertheless, when a non standard scaling equation is used, this will be specified in a SDS attribute called « scaling_equation ».
