Schematic of the driving system for the setup. A Python-based graphical user interface (Python GUI) was used to operate the Unix-based software package SPEC, which was used in turn to control different components of the system. This schematic illustrates the following components: (i) the excitation sources (LEDs and lasers); (ii) the MARCCD data collection software that controls the detector and the beamline shutter; and (iii) the beamline optimization system. The schematic also shows the TTL generator connected to the digital counter card (NI6602 card) that helps drive various excitation sources. The TTL generator box is shown in the inset.
