Figure 7
--------

Figure 7 amalgamates the error results of the 2D planar convective Couette flow SPIDER analyses, which are contained within SPIDERScripts.zip.

7a) combines the errors obtained when running the SPIDER script:-
SPIDER-main/Couette/Vec_2D_library_Ra1e8.m
which are repeated in:-
SPIDER-main/Couette/Vec_2D_library_Ra1e8-u0.5.txt
SPIDER-main/Couette/Vec_2D_library_Ra1e8-u1.0.txt

7b) combines the errors obtained when running the SPIDER scripts:-
SPIDER-main/Couette/Sca_library_Ra1e8.m
which are repeated in:-
SPIDER-main/Couette/Sca_library_Ra1e8-u0.5.txt
SPIDER-main/Couette/Sca_library_Ra1e8-u1.0.txt

This data is plotted in the second tab of the Excel spreadsheet Figures-SPIDER.xlsx
