VIP v0.9.11

Changes since VIP v0.9.10:

• Improved compute_binary_map function
• Updated docstrings in several functions
• Fixed call to deprecated normpdf (matplotlib older version)
• Fixed bug in cube_detect_badfr_ellipticity (to match new photutils API)

VIP v0.9.10

Changes since VIP v0.9.9 :

• New SVDecomposer class, svd module was cleaned up.
• Lots of improvements to vip.pca.pca function for ADI, ADI+RDI or AmSDI datasets. It allows the computation of a grid of results when ncomp is a tuple, the possibility to choose a desired CEVR, and incremental PCA for big arrays. Updated docstrings.
• Improvements to vip.pca.pca_annular function for ADI, ADI+RDI or AmSDI datasets. Updated docstrings.
• Improvements to vip.preproc.cube_recenter_dft_upsampling function.
• Defaults changed in vip.var.fit_2d module.
• Added test modules: test_pipeline_adi, test_pipeline_sdi, test_pipeline_rdi, test_metrics_detection and test_metrics_snr.
• Module vip.metrics.snr_source has been cleaned up. Function snr computed the STD of background apertures with the ddof=1 option.
• Other minor fixes and improvements.

• Improvements in median_sub function
• Improvements in compute_binary_map function
• Redundant function in shapes module were removed. The signatures of several functions were unified
• Changed defaults for xloci least-square model PSF subtraction
• Updated ANDROMEDA algorithm
• Support for Python 3.7
• Improved pytest coverage
• Improved documentation

VIP v0.9.7

Changes since VIP v0.9.6:

• Several model PSF subtraction algorithms are now compatible with ASDI datasets.
• New metrics subpackage with a ROC class.
• Refactoring of multi-processing logic.
• Improvements on the ANDROMEDA implementation.
• Various bugs were fixed.
• Code cleanup.

VIP v0.9.6

This new version of VIP contains the following changes:

• Improved HCIDataset, HCIFrame and a couple of HCI classes. This is part of the new object oriented API to make the functionality of VIP more cohesive.
• A port of the IDL ANDROMEDA algorithm has been added (great job @r4lv).
• Improved centering routines and create_synth_psf function.
• Code cleanup in fits module.
• Improved docstrings of several functions/classes.

VIP v0.9.5

• Introducing new object oriented API (classes HCICube, HCIFrame). Work in progress, to be finished before VIP 1.0.0 release.
• Re-written full-frame PCA algorithm, with improved ADI+mSDI processing.
• Improved 2d fitting (Gaussian, Moffat and Airy disk models). New create_synth_psf function.
• Cube subsampling in 4d case.
• Improved normalize_psf function (psf_norm before)
• Code cleanup and various minor enhancements.
• Documentation cleanup.
• More homogenous plotting style.
