{"success":true,"data":{"ext":"fts","name":"FTS","description":"Flexible Image Transport System (FITS) is a scientific data file format developed by astronomy researchers and maintained through the IAU FITS Working Group and related standards bodies. It is used for storing astronomical images, spectra, tables, and other observational data in observatories, research archives, and analysis software. FITS has a long history in scientific computing and remains widely supported; files are generally safe, though large datasets may require specialized viewers.","mime":["application/fits"],"risk_level":"Safe","signatures":[{"hex":"53 49 4D 50 4C 45 20 20 3D 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 54","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]},{"hex":"53 49 4D 50 4C 45 20 20 3D 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 20 54","offset":0,"sources":[{"name":"Apache Tika","url":"https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml"}]}],"related":["fit","fits"],"usage":{"python":"def is_fts(file_path: str) -> bool:\n    \"\"\"Check if file is a valid FTS by magic bytes.\"\"\"\n    signature = bytes([0x53, 0x49, 0x4D, 0x50, 0x4C, 0x45, 0x20, 0x20, 0x3D, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x54])\n    with open(file_path, \"rb\") as f:\n        return f.read(30) == signature","node":"function isFTS(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x53, 0x49, 0x4D, 0x50, 0x4C, 0x45, 0x20, 0x20, 0x3D, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x54]);\n  return buffer.subarray(0, 30).equals(signature);\n}","go":"func IsFTS(data []byte) bool {\n    signature := []byte{0x53, 0x49, 0x4D, 0x50, 0x4C, 0x45, 0x20, 0x20, 0x3D, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x20, 0x54}\n    if len(data) < 30 {\n        return false\n    }\n    return bytes.Equal(data[:30], signature)\n}"}}}
