A SEARCH FOR STARS OF VERY LOW METAL ABUNDANCE. VI. DETAILED ABUNDANCES OF 313 METAL-POOR STARS (2014, methodology): “…obtained with the Tull Spectrograph and HRS, reduction, extraction, sky and scattered light removal, and wavelength calibration (derived from ThAr exposures taken before or after each stellar exposure) of the spectra were accomplished using the REDUCE software package (Piskunov & Valenti 2002).”
Escape of Lyman continuum radiation from local galaxies - Detection of leakage from the young starburst Tol 1247-232 (2013, methodology): “This is achieved by solving a regularized optimization problem with the solver implemented as an IDL routine: opt_filter_2d.pro, which is part of the Reduce package3 (Piskunov & Valenti 2002).”
The Hamburg/ESO R-process enhanced star survey (HERES) - III. HE 0338-3945 and the formation of the r + s stars (2006, methodology): “The reduction was made in the standard way by using the IDL-package REDUCE, Piskunov & Valenti (2002).”

Spectroscopic Properties of Cool Stars (SPOCS). I. 1040 F, G, and K Dwarfs from Keck, Lick, and AAT Planet Search Programs (2005, methodology): “Automated data reduction pipelines are common now (e.g., Nichols & Linsky 1996; Mulas et al. 2002; Piskunov & Valenti 2002), but automated abundance analysis tools (e.g., McWilliam 1990; Valenti & Piskunov 1996; Erspamer & North 2002) are still rare.”
Atomic Diffusion and Mixing in Old Stars. I. Very Large Telescope FLAMES-UVES Observations of Stars in NGC 6397 (2007, result): “A careful re-analysis of the archival data of G01 for this star using the REDUCE software package (Piskunov and Valenti 2002) pointed towards an effective temperature of Teff =6230K, again in line with the new spectra obtained.”
