ASTAP 并显示可见的实时堆栈标签和选定的路径。 | + +### 命令行参数优先级 + +命令行参数优先于 fits 头文件值。前端程序应提供对 -z 和 -r 选项的访问。-z 的默认值应为 0（自动）。 + +### 典型命令行 + +```bash +astap.exe -f image.fits -r 50 +astap.exe -f c:\images\image.png -ra 23.000 -spd 179.000 -fov 1.3 -r 50 +``` + +对于大多数 FITS 文件，命令行可以很短，因为望远镜位置和视场可以从 FITS 头文件中检索。如果没有 FITS 文件，首选是非无损图像格式，如 .PNG 或 .TIFF 或 RAW 格式，如 .CR2。如果可能，使用 16 位或原始 12 位格式。不要拉伸或饱和，尽可能原始。对于非 FITS 格式，应添加 RA、DEC 位置和 -fov（图像高度，单位为度！！）。 + +如果在 RAW、PNG、TIFF 文件的命令行中未指定 FOV（图像高度，单位为度），ASTAP 将使用程序、堆栈菜单、对齐标签中设置的 FOV。此设置可以通过参数 -fov 0 自动学习和更新。ASTAP 将尝试所有 FOV 在 10 度和 0.3 度之间。例如： + +```bash +astap.exe -f c:\images\image.png -ra 23.000 -spd 179.000 -r 30 -fov 0 +``` + +成功求解后，正确的 FOV 将存储在 ASTAP 设置中。对于下次使用相同来源的图像求解，可以省略 -fov 0 参数，求解将更快。 + +### 调试选项 + +调试选项允许在 GUI（图形用户界面）中设置一些求解参数并测试命令行。在调试模式下，所有命令行参数都已设置，指定的图像显示在查看器中。只需手动给出求解命令： + +```bash +astap.exe -f c:\images\image.png -ra 23.000 -spd 179.000 -r 30 -debug +``` + +或 + +```bash +astap.exe -debug +``` + +### 命令行，输出文件 + +在命令行模式下，程序在与输入图像相同的位置生成两个输出文件。如果找到解决方案，它将写入一个 .wcs 文件 1)，仅包含已解决的 FITS 头文件。在任何情况下，它将使用标准 FITS 关键字写入一个 INI 文件。 + +#### 成功求解后的 INI 输出文件示例 + +```ini +PLTSOLVD=T // T=true, F=false
