What is the .FITS File Extension?

.FITS File Extension Description:

FITS stands for Flexible Image Transport System and files made in this application use the FITS file extension. The FITS file extension is a digital file format that is used to transmit, store, and even manipulate images. The FITS file extension is commonly used in science study. Some users may ask why the file extension FITS is used, instead of other famous or well-known image formats like JPEG and BITMAP. The sole reason for using the FITS format in science is its specialization in storing the scientific data.

The FITS file extension, therefore, does not only include the mere image of the graphic file. It also contains other information, like the many provisions the file uses. This is highly important since photometric and some spatial calibration data, and the origin of the image, are also important data in scientific studies.

With the FITS file extension, users can use the major features of FITS, like its capacity to store image metadata. This data is stored in the ASCII header that can be read by humans. If the user wants to study and examine the headers of the file, he can do so with the FITS file extension in ASCII format. The information included in this ASCII format are the size, coordinates, origin, free-form comments, binary data format, history of the data, and other information that the creator of the file may include.

For non-graphic files, the FITS file extension can be found in the spectra, data cubes, photon lists, and other structure data like multi-table databases. All these various files may have the FITS file extension. The FITS file extension may serve as support for a table document, since FITS also has some tabular information with columns and multidimensional rows. Also, this table has its own specifications.

The FITS file extension can be used with other applications that are also used for scientific studies. Some of these programming languages are C, Java, FORTRAN, Perl, NumPy, PDL, IDL, and S-Lang.
