WINERED WIDE-Mode Spectra of Solar Analogs for Matsunaga et al. 2026

# WINERED Solar-Analog Spectra (science-ready) ## OverviewThis release provides science-ready 1D spectra of solar-analog stars observedwith WINERED. The data are continuum-normalized and include telluric correctioninformation. A combined average calibrator spectrum is also provided. ## Contents- `data.zip` : ZIP archive containing the FITS binary tables of spectra (one file per target, plus a combined spectrum).- `targets.csv` : metadata index for each FITS file.- `accepted_lines_mrt.txt` : machine-readable list of accepted spectral lines used in the abundance analysis, including line depth and the VALD/MB99 atomic data and calibration values. ## Wavelengths- Wavelength unit: Angstrom- Wavelength frame: air (common to all stars)- RV correction applied: yes (common to all stars) ## Flux- FLUX type: normalized (common to all stars)- FLUX unit: dimensionless (common to all stars)- Normalization: continuum ## Telluric information- TELLURIC column stores transmission T (dimensionless) for all stars.- Relationship: `FLUX = FLUX_RAW / TELLURIC`- Telluric method keyword: model ## FITS columns### Per-target spectra- WAVE: wavelength array- FLUX: telluric-corrected, normalized flux- ERR: flux uncertainty- ORDER: echelle order number- TELLURIC: telluric transmission (T)- FLUX_RAW: flux before telluric correction- MASK: 1=masked, 0=good (masked when per-pixel usage count is 0 or invalid) ### Combined spectrum- WAVE, FLUX, ERR: combined mean spectrum and uncertainty- OUT_LO, OUT_HI: outlier clipping bounds used in combination ## targets.csv columnsobject_id, date_obs, mjd_mid, exptime_s, rv_mean_kms, file_fits, notes - `file_fits` gives the path of each FITS file inside `data.zip` (for example, `data/HIP1954.fits`). ## Notes- Combined spectrum uses multiple observation dates (DATE-OBS = MULTI).- Common metadata for all stellar spectra: setting=WINERED, wave_frame=air, rv_corr=yes, flux_type=normalized, flux_unit=dimensionless, telluric_column=TELLURIC, telluric_form=T, has_flux_pre=yes.- The combined spectrum does not include TELLURIC or FLUX_RAW columns.- The FITS files themselves are distributed inside `data.zip`; they are not listed separately in the repository.- `accepted_lines_mrt.txt` follows a fixed-width machine-readable format with a byte-by-byte description in the file header.- See FITS headers for detailed metadata (DATE-OBS, MJD, EXPTIME, etc.). ## CitationPlease cite the associated paper or project documentation when using these data
