摘要
2MASS(Two Micron All Sky Survey)以相当高的内部一致性和精确度在近红外波段对整个天空进行了巡天观测,并通过数据处理把原始数据转变为对天文学有用的图像、星等和位置的列表。较详细介绍了2MASS的科学意义、巡天成果、数据特征以及利用2MASS观测数据所开展的部分工作。
2MASS has revealed the all near-IR sky with remarkable uniformity and accuracy. Through data processing vast amount of raw data were transformed into astronomically useful images and lists of the infrared brightness and positions. This article briefly introduced scientific significance and data feature of the 2MASS project as well as some main research fields using information of 2MASS.
