“…17 and 28 were redone using the Al and Cu Hugoniots as established by Knudson et al 27 as appropriate and the results fit using Orthogonal Distance Regression (ODR). 29,30 We chose ODR (also referred to as Total Least Squares) over ordinary least-squares regression (OLS) to best capture the error in both the U S and u values since they were roughly of equal magnitude.…”

“…The implicit nonlinear weighted orthogonal distance fitting was performed using ODRPACK95 (Zwolak et al 2007), which is an updated version of ODRPACK (Boggs et al 1989). This fitting routine takes into account the uncertainties in the photometry, extinction corrections, parallaxes, [Fe/H] values and periods.…”

We present multi-epoch infrared photometry in the K s -band for 74 bright RR Lyrae variable stars tied directly to the 2MASS photometric system. We systematize additional K-band photometry from the literature to the 2MASS system and combine it to obtain photometry for 146 RR Lyrae stars on a consistent, modern system. A set of outlier stars in the literature photometry is identified and discussed. Reddening estimates for each star were gathered from the literature and combined to provide an estimate of the interstellar absorption affecting each star, and we find excellent agreement with another source in the literature. We utilize trigonometric parallaxes from the Second Data Release of ESA's Gaia astrometric satellite to determine the absolute magnitude, M Ks for each of these stars, and analyze them using the astrometry based luminosity prescription to obtain a parallax-based calibration of M K (RR). Our periodluminosity-metallicity relationship is M Ks = (−2.8 ± 0.2)(log P + 0.27) + (0.12 ± 0.02)([Fe/H] + 1.3) − (0.41 ± 0.03) mag. A Gaia global zero-point error of π zp = −0.042 ± 0.013 mas is determined for this sample of RR Lyrae stars.

A new program for electrochemical impedance analysis has been developed based on the expanded measurement model. The main feature of this program is that it allows the user to easily estimate the equivalent circuit, as well as an initial guess of the fitting parameters, through a graphic user interface (GUI). The function to illustrate the partial impedance spectra is implemented in the graphs of log fZ real and log fZ imag . In this context, f represents the alternating current frequency applied to the sample; Z real and Z imag represent the real and imaginary components of the impedance, respectively. By employing the GUI supporting function, the impedance spectrum can be analyzed without the use of a pseudo-element such as a constant phase element and with an empirical parameter in the Warburg and Gerischer impedance. Based on the results, it is possible to calculate a discrete distribution of the relaxation times from the optimized parameters.
