How to find vortices and remove them from the pressure data
Part 2: called version "2a"
================================================================

1] Find the vortexes: use a vortex table from the vortex analysis of the data
		-> run read_vortex_table.py
			it uses the vortex table "alldrop_ordered.txt"
			it saves i_vortex_2a.npy for all sols
		-> then run find_vortices_v2.py with version = 2a
			it removes vortices from pressure data
			it creates and saves pressure2a.npy
			
2] Plot pressure and vortex removal
	run plot_vortexes.py
	
3] Compute pressure stdev without vortices
	run read_pressure2_novortex(_all).py
	it creates p_dev2a for pmoy=100s and pmoy=1000s
	
4] Correct pdev2 data from interday/holes in acquisition: procedure similar to the doc "readme2_extract_pressure_data.txt" starting at step [2].
-> cut_variable_v2.py (for the 2 cases with fqcy change during the sol: sols 168 and 261)
-> pb_data_missing_autom.py (to add NaNs around missing data)
-> corr_interday_v2.py (interday correction for pdev2)

5] Plot the results
-> plot_p_dev_all.py   [with mod_loopconcat.py & mod_colorplot.py]
-> plot_p_dev_all_all.py   [with mod_loopconcat_v2.py & mod_colorplot_all.py]
