本系统数据来源于云南天文台、紫金山天文台等单位的太阳黑子手描历史资料；
其中，各个台站不同时期的每张手绘黑子图中的数据类型有差异，下面以云南天文台的手绘图来说明，

在太阳黑子信息查询中的高级查询，生成出来的txt文本文件数据说明（空格为分隔符）：
1 日期
2 太阳黑子群号
3 经度(°)
4 纬度(°)
5 黑子类型
6 单个黑子群面积
7 单个黑子群中最大的黑子面积
8 黑子群中质心到太阳日面中心的距离（mm）
9 黑子个数（个）
提示：由于云南天文台数据一致性最高、内容最丰富，高级查询中主要是以查询云南天文台数据为主。

The data of this system comes from the sunspot hand history data of the Yunnan Astronomical Observatory and 
the Purple Mountain Observatory.
Among them, there is a difference in the data types in each hand-drawn black subgraph of each station in different periods.
The following is illustrated by hand-painted pictures of yunnan observatory.

Generated TXT text file data description in advanced queries in sunspot information query(Spaces are delimiters):
1 date
2 Sunspot group number
3 longitude (measurement unit °)
4 latitude(measurement unit °)
5 Sunspot type
6 Single sunspot area
7 The largest black sub-area in a single sunspot group
8 The distance from the center of mass to the center of the solar sun in the sunspot group( measurement unit millimeter)
9 Number of sunspots(measurement unit is number)
Tip: Due to the highest data consistency and richest content of the Yunnan Observatory, the advanced query is mainly based on the query of Yunnan Observatory data.
