Differences between CubeFit for Python and CubeFit for Yorick

CubeFit was originally implemented in the Yorick language. The following paper where using the Yorick implementation:

  • Paumard, Thibaut; Ciurlo, Anna; Morris, Mark R.; Do, Tuan & Ghez, Andrea M. 2022; Regularized 3D spectroscopy with CubeFit: Method and application to the Galactic Center circumnuclear disk; Astronomy & Astrophysics, Volume 664, id.A97; doi: 10.1051/0004-6361/202243228
  • Ciurlo, Anna ; Paumard, Thibaut ; Rouan, Daniel & Clénet, Yann 2019; Clumpiness of the interstellar medium in the central parsec of the Galaxy from H2 flux-extinction correlation; Astronomy & Astrophysics, Volume 621, id.A65; doi: 10.1051/0004-6361/201731763
  • Ciurlo, Anna ; Paumard, Thibaut ; Rouan, Daniel & Clénet, Yann 2016; Hot molecular hydrogen in the central parsec of the Galaxy through near-infrared 3D fitting; Astronomy & Astrophysics, Volume 594, id.A113; doi: 10.1051/0004-6361/201527173

The Python re-implementation has the following notable differences compared to the original Yorick implementation:

  • Cube dimensions in Yorick are X, Y, W; in Python Y, X, W;
  • Yorick uses 1-indexing while Python defaults to 0-indexing;
  • Regularisation term in Yorick is 4 times larger than in Python (multiply delta by 2 and keep delta*scale the same);
  • The Python profile functions return a tuple with the objective function and its Jacobian matrix: profile(x, *a) -> y, jacobian while the Yorick profile functions return the objective function as their return value and the JAcobian as an output parameter: profile(x, a, &jacobian, deriv=) -> y;
  • The multiprofile and offsetlines features have been merged (and Pythonified) in the cubefit.multiprofile.MultiProfile class.
