Evolution of Time Measurement in Astronomy,h is basically cyclical. During many centuries, rather simple devices, such as water clocks or astrolabs and, later on, mechanical clocks, have been used by astronomers for defining realistic but low accuracy time scales. Lately, the atomic time, with its unprecedented precision, has open the way toGuileless 发表于 2025-3-24 17:07:04

IHAP: Image Handling and Processing System,er expert making several instrument control systems. It was implemented on HP 21 MX series computers for which it was highly optimized. IHAP used its own file system for image data and mainly assembler code for low-level routines while applications were written in FORTRAN. This gave it a very high plinguistics 发表于 2025-3-24 23:42:06
FITS: A Remarkable Achievement in Information Exchange, interchange format that is used by virtually all scientists and institutions in the field. The technical and sociological reasons for this success are discussed and a few of the many remarkable scientific results made possible by this information handling are described.
