Executive summary

Find peaks of 1D profiles

Context and background knowledge

• This algorithm will be used in different workflows: calibration (find peaks before fitting to get FWHM) or to remove parasitic peaks.
• A follow-up work could be an implementation in 2D (but it is more challenging)

Inputs

• 1D spectrum as function of ToF or d-spacing or Q
• user input for the algorithm: peak_min, peak_rel_height

Methodology

same as scipy.signal.find_peaks

Outputs

provide same types of output as scipy.signal.find_peaks

Which interfaces are required?

Integrated into reduction workflow, Python module / function

Test cases

Test data file and Jupyter notebook
