Debian Astro Data Reduction packages

This package contains a barebone command-line solver compatible with the GUI version of astap.

No pop-up notifier.

It will not accept raw files and will not work with SharpCap since FOV is not stored.

EsoRex is the European Southern Observatory (ESO) Recipe Execution Tool. It can list, configure and execute CPL-based recipes from the command line.

The Common Pipeline Library (CPL) comprises a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit. It forms a basis for the creation of automated astronomical data-reduction tasks.

One of the features provided by the CPL is the ability to create data-reduction algorithms that run as plugins (dynamic libraries). These are called "recipes" and are one of the main aspects of the CPL data-reduction development environment.

Montage is a toolkit for assembling astronomical images into custom mosaics.

It uses algorithms that preserve the calibration and positional (astrometric) fidelity of the input images to deliver mosaics that meet user-specified parameters of projection, coordinates, and spatial scale. It supports all projections and coordinate systems in use in astronomy.

It contains independent modules for analyzing the geometry of images on the sky, and for creating and managing mosaics; these modules are powerful tools in their own right and have applicability outside mosaic production, in areas such as data validation.

This package contrains software to produce a sharp image of a planetary system object (moon, sun, planets) from many seeing-affected frames using the "lucky imaging" technique._

The program is mainly targeted at extended objects (moon, sun), but it works as well for planets. Results obtained in many tests show at least the same image quality as with the established software AutoStakkert!3.

Input to the program can be either video files or directories containing still images. The following algorithmic steps are performed:

• First, all frames are ranked by their overall image quality.
• On the best frame, a rectangular patch with the most pronounced structure in x and y is identified automatically. (Alternatively, the user can select the patch manually as well.)
• Using this patch, all frames are aligned globally with each other.
• A mean image is computed by averaging the best frames.
• An alignment point mesh covering the object is constructed automatically. Points, where the image is too dim, or has too little contrast or structure, are discarded. The user can modify the alignment points, or set them all by hand as well.
• For each alignment point, all frames are ranked by their local contrast in a surrounding image patch.
• The best frames up to a given number are selected for stacking. Note that this list can be different for different points.
• For all frames, local shifts are computed at all alignment points.
• Using those shifts, the alignment point patches of all contributing frames are stacked into a single average image patch.
• Finally, all stacked patches are blended into a global image, using the background image in places without alignment points.
• After stacking is completed, the stacked image can be postprocessed (sharpened) either in a final step of the stacking workflow, or in a separate postprocessing job.

WeightWatcher is a program that combines weight-maps, flag-maps and polygon data in order to produce control maps which can directly be used in astronomical image-processing packages like Drizzle, Swarp or SExtractor.

Weight-thresholding and/or specific flag selections are applied by WeightWatcher through a configuration file: this alleviates other programs from such interpretation work. WeightWatcher will mostly be useful as part of an imaging survey pipeline. Its main features are:

• Processing speed: limited by the I/O performances of the machine (typically 50 Mpixel/s on a workstation),
• Ability to work with very large images (up to, say, 10^8 × 10^9 pixels on a 64 bit system),
• FITS format (including Multi-Extension) is used for input and output. Output flag-map format selection is automatic (8, 16 or 32bits),
• Up to 30 weight-maps, 30 flag-maps, and thousands of polygons can be handled simultaneously.
• Automatic rasterizing of DS9 .reg files,
• Statistics of flagged and weighted areas,
• Metadata output in XML-VOTable format.

FORS pipeline recipes for the reduction of data obtained with the FORS1 and FORS2 instruments in the LSS, MOS, MXU, PMOS, and direct imaging instrument modes.

FORS is the visual and near UV FOcal Reducer and low dispersion Spectrograph for the Very Large Telescope (VLT) of the European Southern Observatory (ESO). Two versions of FORS have been built, upgraded and moved to the Cassegrain foci of different telescopes in the past years. In April 2009, FORS1 was dismounted to make room for X-shooter, so only FORS2 is in operation. FORS is designed as an all-dioptric instrument for the wavelength range from 330 nm to 1100 nm and provides an image scale of 0".25/pixel (or 0".125/pixel with the high resolution collimator) in the standard readout mode (2x2 binning). FORS2 is installed on UT1 (Antu) and is by default equipped with a detector system that is optimised for the red with a very low level of fringes thanks to a mosaic of two 2k x 4k MIT CCDs (with 15 μm pixels). However, the blue-optimised detector system that was previously available on FORS1 has been commissioned on FORS2 and can be requested for Visitor Mode observation. The geometries of both detector systems are similar, with the optical axis falling ~30" above the gap and offsets of a few arc-seconds between the two chips. FORS2 has many modes, including multi-object spectroscopy with exchangeable masks, long-slit spectroscopy, imaging and spectro-polarimetry and high-time resolution imaging and spectroscopy.
