VSAT-2D Example Dataset

Dataset to run Example.py script of the Valparaíso Stacking Analysis Tool (VSAT-2D). The Valparaíso Stacking Analysis Tool (VSAT-2D) provides a series of tools for selecting, stacking, and analyzing <em>moment-0</em> intensity maps from interferometric datasets. It is intended for stacking samples of <em>moment-0</em> extracted from interferometric datasets, belonging to large extragalactic catalogs by selecting subsamples of galaxies defined by their available properties (<em>e.g. redshift, stellar mass, star formation rate</em>) being possible to generate diverse (<em>e.g. median, average, weighted average, histogram</em>) composite spectra. However, it is possible to also use VSAT-2D on smaller datasets containing any type of astronomical object. VSAT-2D can be downloaded from the github repository link.本数据集用于运行瓦尔帕莱索堆叠分析工具（Valparaíso Stacking Analysis Tool，VSAT-2D）的Example.py脚本。瓦尔帕莱索堆叠分析工具（VSAT-2D）提供了一套用于从干涉测量数据集中选取、堆叠并分析矩0（moment-0）强度图的工具集。该工具旨在针对从大型河外星表提取的干涉测量数据集矩0图样本开展堆叠操作，支持根据星系的已知属性（如红移、恒星质量、恒星形成率）选取星系子样本，并可生成多种类型的复合光谱（如中位数光谱、平均光谱、加权平均光谱、直方图）。不过，VSAT-2D也可用于包含任意类型天体的小型数据集。用户可从该GitHub仓库链接下载VSAT-2D。
