About formats

XPS (XML Paper Specification) is a fixed-layout document format developed by Microsoft, first released with Windows Vista and .NET Framework 3.0 in November 2006. Conceived as Microsoft's alternative to Adobe's PDF, XPS uses XML-based page description markup within a ZIP-based Open Packaging Conventions container. Each page is described as a FixedPage element containing paths (vector shapes with fill and stroke), glyphs (text positioned at precise coordinates), images, and canvas groupings — all specified with exact coordinates for pixel-precise rendering. The format embeds all required resources: fonts are subset and included, images are stored within the package, and the complete rendering specification travels with the document. Windows includes the XPS Document Writer as a virtual printer, allowing any application to generate XPS output through the standard print dialog. One advantage is exact visual fidelity — XPS documents render identically on any compliant viewer because every element is positioned absolutely, with no interpretation variance. Native Windows integration is another strength: XPS viewing, creation, and printing are built into Windows without additional software, and the .NET Framework provides APIs for programmatic XPS generation. While XPS did not achieve the ubiquity of PDF as a universal document format, it remains used in Windows printing infrastructure, enterprise document workflows, and scenarios where the Windows platform provides native end-to-end support.

FTS is a file extension for the Flexible Image Transport System (FITS), the standard data format used in astronomy since 1981 when it was defined by Don Wells, Eric Greisen, and R.H. Harten at the National Radio Astronomy Observatory, and subsequently endorsed by the International Astronomical Union in 1982. FITS was designed from the outset as a self-describing archival format: each file begins with one or more 2880-byte header blocks containing ASCII keyword-value pairs that describe the data's dimensions, coordinate system, observation parameters, and provenance, followed by data blocks in a variety of numeric types — 8/16/32/64-bit integers and 32/64-bit IEEE floating-point values. FITS supports multi-dimensional arrays (images, data cubes, hypercubes), binary tables for catalog data, and ASCII tables, with multiple Header/Data Units (HDUs) that can coexist in a single file. The format handles specialized astronomical data: spectral cubes, radio interferometry visibilities, multi-extension mosaic images from CCD arrays, and time-series photometry. One advantage is scientific rigor: FITS mandates that all metadata needed to interpret the data physically — coordinate transformations (WCS), photometric calibration, telescope and instrument parameters — travels with the file, eliminating the metadata-loss problem that plagues general-purpose image formats in scientific contexts. The format's longevity and institutional backing is another strength — virtually every observatory, space telescope (Hubble, James Webb, Chandra), and astronomical software package (DS9, IRAF, Astropy) uses FITS as its primary data format.
