日面坐标测量

使用数码相机拍摄太阳黑子后,省略了照片扫描过程,数据处理方便许多。新编黑子坐标测量程序sunspot.exe

观测流程:
1)30毫米目镜+数码相机拍摄全日面像

2)停止赤道仪跟踪,在相同焦距下连续拍摄三张间隔15-20秒的照片

3)使用sunspot程序测量黑子坐标

4)执行sunspot,输入观测时间,程序计算太阳物理观测参数


5)点击[太阳黑子数据处理],打开数据处理窗口

6)点击[选择源文件],打开文件对话框,加入用于标定的2到3个图像文件

7)选择图像质量最好的一幅作为生成正视图的源图


8)点击[生成正视图]。程序生成以yyyy-mm-dd-hh.bmp为名的位图文件,大小1200x1200,太阳像位于中心,直径1000像素。太阳自转轴在垂直方向。位图左上角的灰度值包含观测参数的文本信息供编程读出

9)点击[测量坐标],打开任意正视图进行测量

10)在图像显示区光标变为十字,按左键则在黑子坐标栏中显示测量点的日面经度和日面纬度坐标


11)结束后点[测量坐标],系统询问是否在图上标注。如果确定,则在原正视图上标注黑子日面坐标

这样5分钟即可完成测量工作
