Not Resampling the Data

The command APPLY/DISPERSION generates a result table containing the original flux counts of each pixel of the spectrum. This table can be plotted by PLOT/SPECTRUM as in the sequence:

Midas...> APPLY/DISP ccd0020 sp20 @210
Midas...> PLOT/SPEC sp20

which generates a table sp20.tbl containing the pixel values of the row 210 of the image ccd0020.bdf as well as the central wavelength of each pixel. This command is provided as a convenience for some applications when data resampling is not desirable. However the resulting spectral table cannot be processed further by the current package.
