Using the L-test as a diagnostic of the degree of CL in MicroED data, we concluded that EBEC data collected quickly is improved by CL adjustment, but little improvement is seen for data acquired more slowly with higher total fluence. Notably, while CL adjustment did not meaningfully change R merge and I/sigma, structures from CL-adjusted data generally refined to lower R 1 /R wall than their unadjusted counterparts (Figure ). Overall, these metrics indicate that more robust CL adjustments might further enhance the effective dynamic range of low flux fast EBEC data and improve the quality of MicroED structures. Ultimately, a more robust and thorough CL model would be needed for universal CL adjustments.
