Errata on the Calculation of Hot Gas Properties in a Few Li Jiang-Tao's Papers

TL;DR

This paper corrects errors in seven of Jiang-Tao Li's papers caused by script mistakes that led to overestimated hot gas parameters from X-ray spectral analysis, providing updated results and clarifications.

Contribution

It identifies and rectifies specific computational errors in previous publications, updating the scientific record with accurate data and analysis.

Findings

Overestimation of electron density and gas mass by a factor of about 3.16.

Overestimation of thermal pressure by approximately 2.73.

Updated figures and tables reflecting corrected calculations.

Abstract

This is a combination of the errata of seven papers published between 2008 and 2016 with Jiang-Tao Li (JTL) as the first author. All the problems are caused by two mistakes in the original scripts written by JTL used to calculate the physical parameters of the hot gas from X-ray spectral analysis with a thermal plasma code. The mistakes will result in an overestimate of some parameters, such as the electron number density and hot gas mass by a factor of $\sqrt{10}\approx3.162$, and an overestimate of the thermal pressure by a factor of $\approx2.725$. JTL apologizes to the community for the inconvenience caused by these mistakes. We present an update on the text, numbers, figures, and tables of all the seven papers affected by these mistakes. Other papers led by JTL or co-authored papers are not affected.
