pycdata imports datasets from various telescopes/instruments in pycheops (ascl:2312.034), thus providing the facility pycheops lacks to model transits, eclipses, phase curves from other telescopes/instruments and the PSF photometry produced by PIPE (ascl:2404.002). pycdata automatically puts resultant data products into the pycheops cache directory so that it can be directly readable from the pycheops command line.
