Convert FTS to FITS

Understanding the fts and fits file formats

FTS and FITS are both file formats used primarily in astronomy for storing, transmitting, and processing scientific images and data. FITS stands for Flexible Image Transport System and is the most widely adopted standard in the astronomical community. FTS is essentially an older or alternate extension for FITS files, and the two formats are structurally identical. The main difference lies in the file extension: .fts versus .fits.

Why convert fts to fits?

Converting fts files to fits is often necessary for compatibility with modern astronomical software, data archives, and analysis tools, which typically recognize the .fits extension. This simple conversion ensures seamless integration and processing of your astronomical data.

How to convert fts to fits

Since fts and fits files are identical in structure, conversion is straightforward and usually involves renaming the file extension. However, some software can automate this process and verify file integrity.

Recommended software for fts to fits conversion

• FITS Liberator: A free tool for opening and saving FITS files. Simply open your .fts file and use File → Save As to save it with a .fits extension.
• SAOImage DS9: A popular astronomical imaging tool. Open your .fts file, then use File → Save As and select the .fits extension.
• Astropy (Python library): For batch conversion, use Astropy's fits module to read and write files with the desired extension.

Manual conversion method

If you are certain the fts file is a valid FITS file, you can simply rename the file extension from .fts to .fits using your operating system's file manager or the mv command in a terminal:

mv filename.fts filename.fits

Conclusion

Converting fts to fits is a simple process, as both formats are functionally identical. For best results and compatibility, use dedicated astronomical software like FITS Liberator or SAOImage DS9, or simply rename the file extension if you are confident in the file's integrity.
