51% 1) Input filenames are determined by MenuBrowse (first field), MenuBrowseCampaign
52% (second field), or by the stored file name .FileName_1, or as an input of uvmat.
53% 2) These functions call 'uvmat/display_file_name.m' which detects the file series, and fills the file index boxes
54% 3) Then 'uvmat/update_rootinfo.m' Updates information about a new field series (indices to scan, timing, calibration from an xml file)
55% 4) Then fieldname are opened and visualised by the main sub-function 'uvmat/refresh_field.m'
56% The function first reads the name of the input file(s) (one or two) from the edit boxes  of the GUI
57% It then reads the input file(s) with the function read_field.m and perform the following list of operations:

81%%%%%%%%%%%%%%    SCALARS: %%%%%%%%%%%%??%%%
82% scalars are displayed either as an image or countour plot, either as a color of
83% velocity vectors. The scalar values in the first case is represented by
84% UvData.Field.A, and by UvData.Field.C in the second case. The corresponding set of X
85% and Y coordinates are represented by UvData.Field.AX and UvData.Field.AY, and .X and
86% .Y for C (the same as velocity vectors). If A is a nxxny matrix (scalar
87% on a regtular grid), then .AX andf.AY contains only two elements, represneting the
88% coordinates of the four image corners. The scalar name is represented by
89% the strings .AName and/or .CName.
90% If the scalar exists in an input open (image or scalar stored under its
91% name in a netcdf open), it is directly read at the level of Field{1}or Field{2}.
92% Else only its name AName is recorded in Field{i}, and its field is then calculated
93%by the fuction calc_scal after the coordinate transform or after projection on an CheckEditObject
