The input variables are read from the input file. The input file is written with python syntax. The Input file is interpreted as python after a preprocessing The preprocessing was introduced at the time of HST-> PYHST transition to maintaing compatibility with:

• NO/YES meaning 0/1

• items containing FILE in their name can be initialized without using the “” which are otherwise necessary for strings

The input file has to set (some of) the following variables. To setup easily an input file you are suggested to start from one of the examples given in the doc.

DETECTOR_DUTY_OVERSAMPLING = 1

If this parameter is used, one projection acquired over a small angular cone (for continuous acquisition) is considered to be the sum of several projections corresponding to directions regularly spaced inside the small angular cone. The number of different directions is given by DETECTOR_DUTY_OVERSAMPLING. Use this parameter if the number of projections is small compared to the detector size, in the case of continuous acquisition.

DETECTOR_DUTY_RATIO = 1.0

This is the ratio of aquisition time over total time.
