MicroED/3DED datasets of acetaminophen collected with a Ceta camera on Talos Arctica

Continuous rotation data sets were collected on a Talos Arctica (200 kev) equipped with a ceta camera. Each dataset was collected with an approximate flux of 0.17 e-/ Ų/s^-1 which means a total exposure of 20.4 e-/Ų for a 120-degree wedge of data. Delphi was used to rotate the crystal while TEM Imaging & Analysis (TIA) software was used to collect the data.

Datasets were processed in DIALS directly without any conversion. The structure was solved to 0.84 Å with 99% of overall completeness by merging two datasets (attached).
