Astro capstone meeting notes:  Mar 1, 2022

Present: Richmond, Dussault, Lertviwatkul

  Dussault had some issues with format in bibliography
  
     - Richmond has placed some links to resources in the Discord, 
            under "paper" topic; see in particular

  Dussault shows (O-C) diagram

     - has found 15 times of minimum, 1974 - 2015.  Good!
            (some may be times of secondary minimum)
            (can subtract 0.5 from O-C for a secondary minimum,
                 and include with primary measurements; use a different
                 symbol in the graph for any such secondary values)

     - modify the y-axis to be (O-C) in days, not just fractions of period

     - don't forget to add your own measurement -- with different symbol

     - do you see real patterns and trends, or random scatter?
            try to estimate or look up uncertainty in time,
                 use that to judge if trends are real

  Nititee shows (O-C) diagram
 
     - there appears to be a clear linear trend for most of the modern data
            but a few outliers.  Are they secondary measurements,
            or typographical errors?  Please double-check references

     - one paper mentions a bunch of measurements made in 1840 - 1910.
            Can one add them to the modern measurements?
                 Best to make a second copy of (O-C) which includes them,
                 and keep one copy without them.
                 What are uncertainties in the older measurements?


   For next time,

     - please create new and improved (O-C) diagrams

           include your own measurements
           check and double-check outliers

     - read articles I provided to see what one can learn from 
           (O-C) diagrams.  For example,
