• Looked at SODA Manual (MANUAL.pdf) and aspect_ratio.pro, determine y-axis is with the flow. Believe we figured out how angle in example particles is -32 degrees.

• Make figure of orientation angle definition to show Aaron.
• Look for period without orientation, make plots.

• Kendra is concern that it is in canister different in 2020.
• David - If the particle is on 'All-in', do you still get an orientation angle.
• Feed-back - Two, presentation and Thesis. I'm thinking your at 50% for presentation and 20-25 % Thesis.

• Look at the particle-by-particle data to determine answer to 'All-in' Question.
• Total number in histogram, percent of total number of particle.
• Look at the 10-30 second histogram from 2020 case for both high and low concentrations and compare.
