Xmcd Mcd Converter

From Nostalgia to Digital: The Guide to XMCD and MCD Converter Tools

| Input (xmcd) | Output (mcd) | Required conversion | |---------------|---------------|----------------------| | Energy (eV) vs. Δμ (arb. units) | Wavelength (nm) vs. ΔA (mdeg or ΔOD) | Energy to wavelength (1240/E), unit scaling, interpolation | | X-ray absorption spectra (μ+, μ-) | MCD signal (θ_mcd) | No direct physics – but could reformat for plotting | | Binary beamline format (e.g., SPEC, HDF5) | JASCO binary/text .mcd | Header parsing, byte order conversion, metadata mapping |

  • A mis-typing of .xmc (X-ray Magnetic Circular data – rare).
  • A custom format from a synchrotron beamline (e.g., beamline ID08 at ESRF, or ALS Beamline 6.3.1) where users save XMCD data as .xmcd.
  • An ASCII file with two columns (energy, asymmetry) saved with a .xmcd extension by a local script.
  • Possibly related to XMCD analysis software like X MCD (not to be confused with XMCD technique) – no confirmed public tool.

Next Steps:

  • XMCD – Originally associated with Xmcd, a CD player and ripping utility for Unix-like systems (popular in the 90s and early 2000s). XMCD files contain disc information (artist, album, track titles) indexed by CD’s table of contents (TOC).
  • MCD – Often refers to MusicCD database format or cdaudio format used by some Windows/Linux media players and CD database tools. It serves a similar purpose: storing CD metadata for offline lookup.

XMCD:

Introduced with Mathcad 12 through 15, this is an XML-based format. It was designed to be more "open," but it is still specific to the legacy Mathcad engine. xmcd mcd converter
