Many options in the pipeline and its products are set in the config file, pest_pipeline_config.txt . The pipeline expects this to be in your ~/bin directory.
General
Any line that starts with the character ‘#’ is treated as a comment and ignored.
Parameters are set in the form keyword = setting
Settings are case sensitive, so if the comment says ‘Yes’ or ‘yes’ will work, don’t enter ‘YES’. Some settings have a default outcome which is used unless a valid contrary value is entered. For example the default date type is ‘BJD’ and the only valid alternative is ‘HJD’. So ‘date_type = XXX‘ will have the same effect as ‘date_type = BJD‘. Only ‘date_type = HJD‘ results in HJD being used.
At the bottom is text from the config file I use, with additional notes below.
Notes
- If you are not doing work as demanding as for TESS, use ‘simple_mode = Yes‘. This turns off outlier star lightcurve plots, detrending, plate-solving and Gaia checking, and will speed things up considerably. Finder charts will also not be produced. But you will still get the ability to run MagPy and do ensemble photometry. For example I used this for observations to find the rotational period of a star. These were short observations each night but the same target over many nights. Given this objective the only product needed was target photometry data.
- The observatory, telescope and camera names are only used for filling out TESS reports.
- Gaia checking requires an internet connection. If you are working off-line, switch this off.
- De-trending is not of much use at the moment. I would switch this off until this facility is better developed.
