Releases¶
dev¶
Features
- Added new
CambGrowthgrowth factor model, which computes the growth using CAMB. This is useful especially when using w > -1, for which the other growth factor models are inadequate. Solves issue #19 raised by @tijmen. - Added new module
mass_definitionswhich more robustly deals with various halo mass definitions, and also includes ability to convert mass functions between different definitions.
Enhancement
- Added get_dependencies method to _Framework, to enable finding all parameters that a quantity depends on.
Bugfixes
- When using camb for the transfer function, some cosmologies would lead to a segfault (i.e. when Ob0 or Tcmb0 are not set explicitly). This now raises a helpful error.
Internals
- Removed logging, which was redundant.
- Moved from nose to pytest
- Significant overhaul of package structure to more modularised form.
v3.0.3 [1st Dec 2017]¶
Bugfixes
- Fixed usage of deprecated MsolMass in wdm
- Fixed Bhattachrya fitting function (thanks to Benedikt Diemer!)
- Fixed typo in Watson fitting function (thanks to Benedikt Diemer!)
- Update cosmo test to use new Astropy constants.
- Fixed issue with sampling function where zeros in ngtm would yield an error.
v3.0.1 [31st Oct 2017]¶
Enhancement
- Normalised all <>_model properties to be actual classes, rather than either class or string.
- Added consistent checking of dictionaries for <>_params parameters.
v3.0.0 [7th June 2017]¶
Features
- Now provides compatibility with Python 3.x. Support for 2.x will be removed in hmf v3.1 (whenever that comes).
- Complete overhaul of the caching system. Should be invisible to the user, but streamlines writing of framework code considerably. Removes required manual specification of dependencies between quantities, and adds ability to specify parameter kinds (model, param, res, option, switch).
Bugfixes
- Fixed bug in Caroll1992 GrowthFactor class which affected high-redshift growth factors (thanks to Olmo Piana).
- Fixed astropy dependency to be >= 1.1
- Fixed bug where Takahashi parameters were always passed through regardess of
takahashisetting. - Fixed small bug where the functional.get_label method returned differently ordered parameters because of dicts.
- Note that the fitting subpackage is temporarily unsupported and I discourage its use for the time being.
Enhancement
- Completely removes dependence on archaic pycamb package. Now supports natively supplied python interface to CAMB.
Install camb with
pip install --egg camb. This means that much more modern versions of CAMB can be used. - Many new tests, to bring total coverage up to >80%, and continuous testing on Python 2.7, 3.5 and 3.6
v2.0.5 [12th January 2017]¶
Bugfixes
- Fixed bug in GrowthFactor which gave ripples in functions of z when a coarse grid was used. Thanks to @mirochaj and @thomasguillet!
Enhancments
- Streamlined the caching framework a bit (removing cruft)
- Totally removed dependency on the Cache (super)class – caching indexes now inherent to the called class.
- More robust parameter information based on introspection.
v2.0.4 [11th November, 2016]¶
Bugfixes
- IMPORTANT: Fixed a bug in which updating the cosmology after creation did not update the transfer function.
v2.0.3 [22nd September, 2016]¶
Bugfixes
- SharpK filter integrated over incorrect range of k, now fixed.
Enhancments
- WDM models now more consistent with MassFunction API.
- Better warning in HALOFIT module when derivatives don’t work first time.
v2.0.2 [2nd August, 2016]¶
Features
- Added a bunch of information to each hmf_model, indicating simulation parameters from which the fit was derived.
- Added
FromArraytransfer model, allowing an array to be passed programmatically for k and T. - Added
Carroll1992growth factor approximation model.
Enhancments
- how_big now gives the boxsize required to expect at least one halo above m in 95% of boxes.
Bugfixes
- Removed unnecessary multiplication by 1e6 in cosmo.py (thanks @iw381)
- IMPORTANT: normalisation now calculated using convergent limits on k, rather than user-supplied values.
- IMPORTANT: fixed bug in Bhattacharya fit, which was multiplying by an extra delta_c/sigma.
- fixed issue with
nonlinear_massraising exception when mass outside given mass range.
v2.0.1 [2nd May, 2016]¶
Bugfixes
- Corrects the default sigma_8 and n (spectral index) parameters to be from Planck15 (previously from Planck13), which corresponds to the default cosmology. NOTE: this will change user-code output silently unless sigma_8 and n are explicitly set.
v2.0.0¶
v2.0.0 is a (long overdue) major release with several backward-incompatible changes. There are several major features still to come in v2.1.0, which may again be backward incompatible. Though this is not ideal (ideally backwards-incompatible changes will be restricted to increase in the major version number), this has been driven by time constraints.
Known issues with this version, to be addressed by the next, are that both scripts (hmf and hmf-fit) are buggy and untested. Don’t use these until the next version unless you’re crazy.
Features
- New methods on all frameworks to list all parameters, defaults and current values.
- New general structure for Frameworks and Components makes for simpler delineation and extensibility
- New growth_factor module which adds extensibility to the growth factor calculation
- New transfer_models module which separates the transfer models from the general framework
- New Component which can alter dn/dm in WDM via ad-hoc adjustment
- Added a Prior() abstract base class to the fitting routines
- Added a guess() method to fitting routines
- Added ll() method to Prior classes for future extendibility
- New fit from Ishiyama+2015, Manera+2010 and Pillepich+2009
Enhancments
- Removed nz and z2 from MassFunction. They will return in a later version but better.
- Improved structure for FittingFunction Component, with cutmask property defining valid mass range. NOTE: the default
MassFunction is no longer to mask values outside the valid range. In fact, the parameter
cut_fitno longer exists. One can achieve the effect by accessing a relevant array as dndm[MassFunction.hmf.cutmask] - Renamed some parameters/quantities for more consistency (esp. M –> m)
- No longer dependent on cosmolopy, but rather uses Astropy (v1.0+)
- mean_dens now mean_density0, as per Astropy
- Added exception to catch when dndm has many NaN values in it.
- Many more tests
- Made the cosmo class pickleable by cutting out a method and using it as a function instead.
- Added normalise() to Transfer class.
- Updated fit.py extensively, and provided new example config files
- Send arbitrary kwargs to downhill solver
