Query: FITSH -- a software package for image processing   In this paper we describe the main features of the software package named
FITSH, intended to provide a standalone environment for analysis of data
acquired by imaging astronomical detectors. The package provides utilities both
for the full pipeline of subsequent related data processing steps (incl. image
calibration, astrometry, source identification, photometry, differential
analysis, low-level arithmetic operations, multiple image combinations, spatial
transformations and interpolations, etc.) and for aiding the interpretation of
the (mainly photometric and/or astrometric) results. The package also features
a consistent implementation of photometry based on image subtraction, point
spread function fitting and aperture photometry and provides easy-to-use
interfaces for comparisons and for picking the most suitable method for a
particular problem. This set of utilities found in the package are built on the
top of the commonly used UNIX/POSIX shells (hence the name of the package),
therefore both frequently used and well-documented tools for such environments
can be exploited and managing massive amount of data is rather convenient.
