Multifitting v.1.10.2

Supports reflectometry and transmission simulation.

• Files Sc_larruquert.nk, ScSi.nk, Sc5Si3.nk, Sc3Si5.nk are added to the database of optical constants
• The ranges of MoSi2.nk and Sc.nk are extended
• Subrange of experimental data can be set for fitting.
• The ability to duplicate structure tabs has been added.
• Visualization of structure profile has been added.
• The ability to calculate the permittivity profile with its discretization into thin sublayers has been added.
• The ability to export an already loaded experimental curve back to a text file has been added.
• The ability to fit a scaling intensity factor for experimental curves has been added.
• It is possible to eliminate the moiré distortions of the calculated curve arising when the period of oscillations of reflection from thick structures is almost a multiple of the step of the experimental curve.
• An automatic calculation of the spectral width of the reflection peak when calculating the corresponding curve has been added.
• Various bugs are fixed, including a fitting bug for a scaled experimental curve.

Multifitting v.1.10.0

Supports reflectometry and transmission simulation.

• Various bugs fixed.
• The graphical interface now supports scaling from the operating system.
• Updated angular and spectral resolution. Now the resolution values that were set in versions
  <1.9.2 should be multiplied by 2. Now the thin line is blurred into a wide one with FWHM ≈ the
  given resolution.
• Angular and spectral resolution each act on both types of curves: spectral and angular (according
  to a simplified scheme).
• The initial and final intensities of the probe beam with linear interpolation between them are
  specified.
• Warning when overwriting files from previous versions.
• Additional options are available for graphs: header with measurement parameters, logarithmic
  scale for the X axis.
• Information can be shown/hidden in the Settings window of the context menu of the “Plots”
  window.
• Instant recalculation when switching on/off structural items in the table if the "Recalculate"
  modifier is enabled.
• The plots in the “Plots/Measured” window are assigned serial numbers that allow you to correlate
  the curve with the loaded data.
• Added the ability to maximize the integral under the reflection curve with the source function.
• Added settings for fitting algorithms.
• Decimal separators in data files - dots and commas.
• Files added to the database of optical constants: Cr_delmotte.nk, Pt_soufli.nk, Be_svechnikov.nk
