	*		*Met with Simon last week to take detector measurements:
			**Measured stack thickness and recorded sheet order for UCLH beam test.
			**Briefly tested cross-talk with UCLH setup – little to none observed.
			*Investigated source of noise "pulsing" observed during UCLH beam test, results record in [ this page].
			**Pulsing largely due to external electronic noise from 50Hz mains.
			**CMOS sensor amplifies external noise.
			**Grounding detector enclosure significantly reduces noise, even in lab conditions.
			*Software developments:
			**Added argument to all plotting routines to set y-scale range. Setting to 0 sets the default range.
			**Added argument to averaged replay script to set the averaging rate (separate to frame rate).
			**Added argument to stepped replay script to choose which measurement to start from and the number of measurements to replay. Last measurement persists on screen.
			**Live plot and fit can now accept background and shoot-through measurements to plot calibrated data.
			***Calibrated data written to file accessed by Bortfeld page on web GUI.
			*Completed analysis of photodiode data from [http://www.hep.ucl.ac.uk/pbt/wiki/Proton_Calorimetry/Experimental_Runs/2021/Apr15 UCLH beam test], results discussed in [ this presentation].
			**Due to signficant electronic noise, better not to do background subtraction.
			**Best fit results came from not performing any correction of pulsing observed from electronic noise.
			**Fit results similar for high and low current results. Should be able to do direct comparisons with CMOS sensor.
			**Wrote macro to read reference curves from UCLH. Emailed Andy asking for required x-axis offset to compare with measurements made in detector.
			*Will analyse CMOS sensor data for next week.
