Convert FTS to PHM

The Flexible Image Transport System (FTS) file extension, is predominantly utilized for the storage, transmission, and manipulation of scientific and astronomical data. Developed by NASA in the late 1970s, this standardized format facilitates data interchange among the astronomical community. FTS is highly extensible, supporting various data types such as images, tables, and multidimensional arrays. Its widespread adoption stems from its capability to encapsulate metadata efficiently, enabling accurate and effective exchange of complex datasets among researchers and institutions.

The PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.
