CosmicProfiles v1.4.0

• Fixes
  • floating point limitations led to incorrect centres being calculated
  • returned centres could lie outside of box, in this release translate back into box before returning
• New Features
  • density profile fitting
    • allow user to choose minimization algorithm, e.g. 'Powell' or 'TNC' etc.
    • allow user to fix parameter, e.g. alpha=0.18 while fitting
  • structured numpy arrays allow easier access to shape profiles
  • katz_config parameters bundled into dictionary; arguments of DensShapeProfs better organised
  • convenience feature ‘kpc/h’ etc for units

CosmicProfiles v1.3.1

• Fixes
  • create cat and viz directories automatically if missing
  • box size read off from Gadget I, II or HDF5 file rather than having to be provided
  • much less RAM-heavy
• New Features
  • made compatible with Gadget-style I, II and HDF5 files

CosmicProfiles v1.2.7

• Fixes
  • unit system confusions resolved by allowing user to define ingoing and outgoing unit system
• New Features
  • choosing either dark matter, gas or star particles in Gadget HDF5 snapshots via OBJ_TYPE
  • choosing number of mass bins for plotting purposes
  • restricting to halos in the index range select = [idx_1, idx_2]

CosmicProfiles v1.2.6

• Fixes
  • caching with modifiable maxsize
  • ellipsoidal shell based shape estimation had poor if-else condition distinguishing innermost from other shells incorrectly
  • density profile model parameter array had somewhat arbitrary ordering, fixed by dictionary
• New Features
  • choosing between reduced shape tensor and non-reduced one
  • ellipsoidal shell based density profile estimation
