v0.1 (2019-05-29)

  • Initial release.

Performance improvements

Version 0.2 introduced a few performance improvements when Lightcurve objects are created. Once the user defines either the counts per bin or the count rates, the other quantity will be evaluated _lazily_, the first time it is requested. Also, we introduce a new low_memory option in Lightcurve: if selected, and users define e.g. counts, countrate will be calculated _every_time it is requested, and will not be stored in order to free up RAM.
