If a response to light exposure is observed, the quality of the data being collected can be assessed. A number of such correlation plots both for synchrotron and in-house pump-probe data collection are presented. © International Union of Crystallography, 2017. %G English %L hal-01618789 %U https://univ-rennes.hal.science/hal-01618789 %~ CNRS %~ UNIV-PSUD %~ STATS-UR1 %~ INC-CNRS %~ UNIV-PARIS-SACLAY %~ UNIV-PSUD-SACLAY %~ TEST-UNIV-RENNES %~ UNIV-RENNES %~ GS-HEALTH-DRUG-SCIENCES %~ IGPS %~ TEST2-HALCNRS
