v53 v54 279 279 === 4.6 Succession of operations: === 280 280 The following succession of operations is performed by '''uvmat.fig''': 281 281 282 -'''File identification:''' the nomenclature type and file type (for instance image, movie, or Netcdf file) are identified from the opened file (using the function ''find_file_series.m''). 283 282 284 -'''File Reading:''' the input field is first read from the input file by the Matlab function ''read_field.m''. 285 283 286 -'''Second file reading:''' The second input field is similarly read if selected. Note that it is kept in memory, so it is not read again if the file is unchanged (this is useful in the case of substraction of a fixed background for instance). 284 -'''Transform:''' by default the 'phys' option transforms each of the input fields from pixel to physical coordinates. This operation can also combine two input fields. 287 288 -'''Transform:''' by default the 'phys' option transforms each of the input fields from pixel to physical coordinates. This operation can also combine two input fields. 289 285 290 -'''Histogram:''' This is obtained from the input field in transformed coordinates, or if applicable from the fields resulting from the two input fields. 286 -'''Projection:''' on the projection object selected in the menu '''[ListObject_1]''', see [#ProjObject section 6]. A second projection, on the object selected by '''[ListObject]''', can be plotted in the ancillary figure '''view_field.fig'''. Projection is performed by the function {proj_field.m}. -'''Field calculation:''' a scalar can be calculated after projection, as selected by the menu '''[Fields]'''. 291 292 -'''Projection:''' on the projection object selected in the menu '''[ListObject_1]''', see [#ProjObject section 6]. A second projection, on the object selected by '''[ListObject]''', can be plotted in the ancillary figure '''view_field.fig'''. Projection is performed by the function {proj_field.m}. 293 294 -'''Field calculation:''' a scalar can be calculated after projection, as selected by the menu '''[Fields]'''. 295 287 296 -'''Field comparison''': when two fields of the same nature are introduced, the difference is taken by the function {sub_field.m.}. This is skipped if the transform function has already led to a single field. 297 288 298 -'''Plotting:''' plot the results of projection. The function {plot_field.m} is used. 289 299
