May 1999: 2.1
- Mostly bug fixes and experimental stuff added
April 1998: 2.0
- New documentation
January 1997 - March 1998:1.2
- Rewriting of an important part of the software, in order to
prepare the future... Further optimization of many functions:
V1.2 is 30 to 500% faster than V1.0.
- (natural) bicubic spline interpolation added to the background-map
processing.
- Possibility to use another FITS frame for detecting objects,
allowing pixel-to-pixel colour measurements.
- New MAG_AUTO magnitudes, more robust towards contamination by
neighbouring sources (MASKing option).
- New .sex format.
- New CHECKIMAGE_TYPEs: MINIBACKGROUND (produces small background maps),
BACKGROUND_RMS (produces noise maps)
MINIBACK_RMS (produces small noise maps)
IDENTICAL (useful for converting data types)
-OBJECTS (background and detections removed).
- Multiple CHECKIMAGE output.
- New astrometric parameters using the WCS library.
- Handling of external flag-maps.
- Handling of images with variable S/N and external noise- or weight-
maps, with interpolation.
- Real-time cross-identification with an ASCII catalog.
May 1996: 1.1 "DeNIS" version (not distributed officially)
- Corrects 2 fatal bugs which sometimes appeared with DEC-Alphas
- Incorporates a new extended FITS output format.
- Added possibility to measure within multiple apertures.
May 1995: Passed 1.0a version: -> FIRST OFFICIAL RELEASE!!! <-
- Now the NNW filename is correct in FITS catalog headers.
- Corrected a convolution bug with large masks at the bottom of
the frame. Added a better-than-nothing normalization of
zero-sum masks.
- Display of the FITS ID limited to 20 characters.
- New default.nnw enhanced and with a larger seeing range.
- FWHM parameters slightly tuned for undersampled profiles.
- The ``sexcopy'' SExTool put in the previous archive wasn't the
right one! Replaced.
- 2 new SExtools released: sexreduce and sexin.
Apr 1995: FIRST 1.0 version:
- Neural-network based star/galaxy classifier implemented. NNW-file
for Moffat-like PSFs in the optical, generated from simulations.
- User's manual updated.
- FWHM_IMAGE, FWHM_IMAGE and ELONGATION parameters added.
- many more typical convolution files included in the archive.
- Comments (beginning with a `#') are now allowed within all the
configuration files.
- 2 SExTools released: sexcat and sexcopy.
- Alpha VMS version added (thanks to R. Johnstone).
Feb 1995: 1.0 beta 5e version:
- 2 bugs major corrected: background interpolation when very special
convolution masks are used, and (fixed) aperture magnitude (improved
to sub-pixel integration).
- Possibility to change preference keywords from the command line.
Dec 1994: 1.0 beta 5 version:
- Major update! Too many changes to mention.
- Code optimized and much more stable now.
- New executables for IBM RS6000 and AMIGA added.
- "II" dropped: call me simply "SExtractor" now.
Sep 1994: 1.0 beta 4 version:
- "clean" distribution with source and makefiles for DEC Alpha,
HP/UX, and SUN workstations.
- SATUR_LEVEL keyword added.
- FLAGS parameter now reliable and written in decimal in ASCII cat.
- KRON_RADIUS parameter now reliable.
- MAG_ISO_ERR and MAG_APER_ERR now give trusty estimates.
- BACKGROUND parameter now in "raw" units.
- catalog index numbering starts now from 1.
- 2 huge fatal bugs corrected in deblending and background estimation
procedures.
Jun 1994: 1.0 beta 3 version: many bugs corrected thanks to enthousiastic
testers! First public release.
May 1994: 1.0 beta 2 version: reads now all kinds of FITS data. C code
completely rewritten in ANSI; image bitmaps are now stored in
floating-point. Now controlled through configuration files.
User's manual written.
Feb 1994: 1.0 beta 1 version of "Sextractor II", still limited to 16 bits FITS
frames, but pipelined processing allows now frames with size up to
65534x65534 to be processable on most machines.
Mar 1993: final version of "Sextractor I": limited to 16 bits 2048x2048 max. FITS
frames, specifically oriented toward Schmidt plate data processing.
Has reduced more than 1.2e10 pixels within 10 months...
