YAML Instrument Section

Below is an example. There are several sections.

• beam: defines the beam properties
  • energy: in keV
  • vector: direction of beam in polar coordinates
• calibration_crystal: this section will moved out of the instrument into a calibration options section
• detectors: defines multiple detectors for the HEDM instrument; user provides a list of sections indexed by panel ID, with these values:
  • distortion: defines function_name and parameters
  • pixels: defines columns, rows and size (two values)
  • saturation_level
  • transform: a translation vector (t_vec_d) and a list of tilt angles (tilt_angles)
• oscillation_stage: defines chi and t_vec_s
