HOWTO: Scan area detector v. motor(s), view data afterwards

[prjemian]

For commissioning activities, users want to make engineering scans with area detectors for various purposes and view the data from those scans right away.

Make a HOWTO document with these goals:

• [ ] use EPICS motor(s)
• [ ] use EPICS area detector
  • [ ] For each image
  • [ ] Write image to HDF5 file.
  • [ ] Measure total counts in image.
  • [ ] Measure maximum counts in image.
  • [ ] Note the image's "unique ID".
• [ ] Step scan motor and collect $n$ image frame(s) at each step.
  • [ ] count
  • [ ] scan with one motor
  • [ ] scan with two motors
  • [ ] grid_scan
• [ ] Collect data in a SPEC data file.
