RAMCO SMB is 0 from 1986 through 1989 #18

Closed mankoff closed 2 years ago

See flat red line at beginning of top panel

It appears to be excluded from 3-RCM average meaning this is not a significant bug.

Reason: 1986 through 1989 files are different:

The fix modified Fig A1 (original above; modified below), and Figs. 3, 5, B1 and D1. Other than A1, there was no noticable graphical changes when including RACMO 1986 through 1989. Changes to the text can be seen in the commit message above.
