Astlib

-------------

* Python 2.6-3.2 now supported.

* Fixed bug in effective wavelength calculation (1 per cent effect depending on band).

* Changed h, m, s in image plot labels to non-italic.

* Added choice of interpolation used in ImagePlot.

* Added OmegaLz, OmegaRz, and updated Ez, Ez2 functions to account for radiation density.

* Added shiftRADec function.

* Added a workaround for bug in handling ZPN projections if PV2_3 == 0.

* Updated astWCS to avoid using a depreciated function in pyfits 3.0+.

-------------

* Bug fix: doing e.g. 'from astLib import astWCS' no longer pulls in e.g. pylab from the other modules.

-------------

* Thanks to an upgrade of the WCSTools C-routines, WCSs with polynomial distortion coefficients (i.e. with
PVi_j type header keywords) are now supported transparently (thanks to Wes Fraser for help with this).

* Fixed bug with handling WCSs with SIP distortion coefficients (i.e. A_i_j, B_i_j type header keywords;
thanks to L.W. Piotrowski for this one).

* Fixed convergence bug in astCoords.calcRASearchBox() at high declination.

* Fixed scalebar length bug and placement of scalebar and compass objects in plots should be much improved.

-------------

* astWCS.WCS.wcs2pix() now gracefully handles RA wraparounds in e.g. CEA images that cover > 180 degrees.

* Added routines to convert from Jy <-> AB mag (Jy2Mag, mag2Jy) in astSED

* Some miscellaneous bug fixes in astSED - renamed renormaliseToMag() -> normaliseToMag(), fixed BC03Model()
to read galaxevpl files with arbitrary number of ages, force age > 0 in makeModelSEDDict()

* Fixed bug parsing non-standard FITS headers in astWCS.WCS

* Added more input unit options to astSED.Passband()

* Added astCoords.calcRASearchBox() function (handy for freeform SQL queries of e.g. SDSS, UKIDSS)

-------------

* astPlots.ImagePlot now works under python 2.6 - this bug was related to the WCS <-> pixel coordinate
conversion routines handling of numpy arrays (now fixed).

* Fixed tick label bug in astPlots.ImagePlot around dec == +/- 00 degrees, when using sexagesimal labels
(thanks Toby).

* astCoords.calcAngSepDeg() now accepts and returns arrays - this makes it easy (and fast) to sort a bunch
of objects by radial distance from some point.

* Removed the astSED.SED.calcAbsMag(), astSED.SED.calcAppMag() functions and replaced with
astSED.SED.calcMag(), with option to add distance modulus.

* Fixed bug in flux calculation from SEDs.

* Vega and AB SEDs are now in physical units. Added Sun (SOL) SED.

* Can now apply Calzetti et al. (2000) extinction law to SED objects.

* Rewritten, fast SED fitting code in astSED module. Several new related functions (flux2Mag(), mag2Flux()
etc.)

* Changed astImages.clipImageSectionWCS() and astImages.clipUsingRADecCoords() to additionally return the
corresponding pixel coordinates in the parent image to the clipped section.

-------------

* Fixed bugs in NEDQueryPlot.py, MStarEvolution.py example scripts.

* Fixed bug when handling HIERARCH keywords (thanks to Stefano). This also fixes bug when handling headers
made by astrometry.net (I believe).

* Added TopHatPassband class to astSED.

* Changed so that PIL only imported in the couple of routines it is needed by (and got rid of annoying
warning message when PIL not installed).

* Fixed the occasional rounding error appearing in astPlot axis labelling.

* Improved default y-axis scaling for astSED plotting function. Added SED integrate function.

* Added astCalc.dVcdz() - calculates volume element for given cosmology and redshift.

* Some updates in the astSED module to work with changes in scipy 0.7.x interpolation routines.

* Fixed astImages.scaleImage() to work with CRDELTi keywords (thanks to Ben Keller for this).

* Some code has been added towards fitting SEDs in the astSED module - this code is not fully tested yet
(astSED.fitSEDDict()).
