0.3.3 (2014-09-23)
------------------

* Fix a simple version error (BAW).

0.3.2 (2014-09-23)
------------------

* Change how version is set (BAW).
* Updated target numbers.

0.3.1 (2014-07-23)
------------------

* Also updated quicksim sn-spec* file output, using IDL version which is slightly
  more optimistic than the python version (diff is dark current?) (SJB).

0.3 (2014-07-23)
----------------

* Updated throughput files for real.
* Added initial "compare_versions.py" script to make it easier to visualize
  differences in versions.  This script should grow as various parameters
  change; right now it only makes a thoughput difference plot (SJB).
* Updated throughput files from 0334v3 (spectro) and 0347v5 (system throughput)
  Correction: thoughput files didn't make it into that change (SJB, 2014-07-08).
* Updated psf-b.fits and psf-quicksim.fits to match new npix_y for blue
  STA/ITL CCDs (SJB, 2014-07-08).

0.2 (2014-07-08)
----------------

2014-07-07 SJB
~~~~~~~~~~~~~~

* Added ELG spectrum with continuum and multiple emission lines

2014-07-07 David Kirkby
~~~~~~~~~~~~~~~~~~~~~~~

Python quicksim

* add readnoise contributions in quadrature during the downsampling
* Refactor for speed, results now named ndarray, updated plots
* Allow different base directories

2014-07-02 DJS
~~~~~~~~~~~~~~

* Put sky back to dimmer UVES sky model

0.1 (2014-07-01)
----------------

2014-06-29 SJB
~~~~~~~~~~~~~~

* Extended fiberloss range from 3500-10000 instead of 3600-10000
* Added data/throughput/fiberloss-qso.dat (same as fiberloss-star.dat)

2014-06-27 SJB
~~~~~~~~~~~~~~

* Updated data/focalplane/platescale.txt with latest from DESI-0329v14.
  This includes a new "theta" column.
* Updated desi.yaml from DESI-0347v4.  This removes the FWHM and wavemin/max
  params which are not derived quantities associated with the PSFs.
* Updated throughput files with new numbers from DESI-0347v4.
* Updated spectrograph throughput files with new numbers from DESI-0334v2.
* Updated py/fiberloss.py -> bin/fiberloss.py .  Biggest change is ELG
  half light radius 0.35" -> 0.45" which drops us below 7-sigma.
* Updated data/throughput/fiberloss-\*.dat files with calculation based
  upon fiberloss.py
* bin/psf2quicksim.py extracted PSF parameters needed for quicksim.
    - pro/desi_quicksim.pro updated, but it still treats FWHM as constant
      rather than wavelength dependent.
    - python quicksim will be broken until it is updated to use new inputs.
* Reorganized data/inputs/throughput/
* spots2psf.py: leftover spot mirroring bug removed, PSFs updated

2014-06-12 SJB
~~~~~~~~~~~~~~

* Updated throughputs to not double count central obscuration.
* Updated PSF files to remove throughputs to avoid possible inconsistency.
* Added wavemin_all, wavemax_all to desi.yaml with min/max wavelength
  seen by all spectra

2014-06-06 SJB
~~~~~~~~~~~~~~

* Updated CCD pixel dimensions and regenerated PSFs to match.
