PanSTARRS DR1 Broad Morphology Catalog

This is a broad morphology (spiral or elliptical) catalog of images identified as galaxies from the first data release of PanSTARRS (PS1 DR1). Annotations were produced by a deep neural network based on the LeNet-5 architecture, and training labels were obtained using "superclean" Galaxy Zoo annotations.<br>The catalog contains labels for 1,662,190 images and has approximately 95% overall accuracy. The dataset is a csv file (with headers) containing the following columns:<b>objid</b> (string): The object ID of the image assigned by PanSTARRS.<b>ra</b> (float): The object's right ascension.<b>dec</b> (float): The object's declination.<b>prob_sp</b> (float): The probability of the galaxy being spiral.<b>prob_el</b> (float): The probability of the galaxy being elliptical.<b>spiral</b> (integer): If prob_sp is greater than prob_el, this is 1; otherwise, it is 0.<b>elliptical</b> (integer): If prob_el is greater than prob_sp, this is 1; otherwise, it is 0.

本数据集为基于泛星计划（PanSTARRS）第一期数据发布（PS1 DR1）中已被识别为星系的图像构建的螺旋/椭圆星系形态学分类目录。
该目录的标注由基于LeNet-5架构的深度神经网络生成，训练标签则通过"superclean"星系动物园（Galaxy Zoo）标注集获取。
本目录共包含1,662,190张图像的分类标签，整体准确率约为95%。
本数据集为带表头的逗号分隔值（CSV）文件，包含以下列字段：
**objid**（字符串型）：由泛星计划分配的图像目标ID；
**ra**（浮点型）：目标的赤经（right ascension）；
**dec**（浮点型）：目标的赤纬（declination）；
**prob_sp**（浮点型）：该星系为螺旋星系的概率；
**prob_el**（浮点型）：该星系为椭圆星系的概率；
**spiral**（整型）：当prob_sp大于prob_el时取值为1，否则为0；
**elliptical**（整型）：当prob_el大于prob_sp时取值为1，否则为0。
