Science Ready Spectra Of Star Clusters And Their Best-Fitting Models Described In The Research Paper "Using Star Clusters As Tracers Of Star Formation And Chemical Evolution: The Chemical Enrichment History Of The Large Magellanic Cloud" By Chilingarian & Asa'D

Science ready spectra of star clusters in the Large Magellanic Cloud and their best-fitting templates (alpha-enhanced MILES based simple stellar population models) obtained using the NBursts full spectrum fitting code. Each spectrum is presented as a binary FITS table, which contains a spectrum (wavelength, flux, uncertainties), best-fitting template, best-fitting parameters (radial velocity, age, metallicity), and a pixel mask used in the fitting procedure. For each cluster, 5 spectra are provided, which correspond to [alpha/Fe] values from 0.0 to 0.4 dex with a step of 0.1 dex. The only exception is NGC2249, for which only 3 models are provided. The alpha-enhancement value of a model grid used in the fitting procedure is given in the FITS keyword MGFEGRID.本数据集收录大麦哲伦云内恒星团的科学可用光谱，以及采用NBursts全光谱拟合代码得到的对应最优拟合模板（基于MILES的α增强型简单恒星种群模型）。每条光谱均以二元FITS表形式存储，其中包含光谱数据（波长、流量、不确定度）、最优拟合模板、最优拟合参数（视向速度、年龄、金属丰度）以及拟合过程中使用的像素掩模。每个恒星团对应提供5条光谱，分别对应[α/Fe]值从0.0到0.4 dex、步长为0.1 dex的模型。仅有一个例外：NGC 2249仅提供3个模型。拟合过程中使用的模型网格的α增强度数值，可通过FITS表头关键字MGFEGRID获取。
