Changelog & to-do¶
Changelog¶
- v0.3.0 July 2019, R.G. van Holstein:
- Added command-line option to mean-combine final images of different observation blocks
- v0.2.1 June 2019, R.G. van Holstein:
- Added the possibility to reduce data taken with the narrowband filters using the existing model of the broadband filters

- Release of IRDAP package on PyPI and GitHub
- Documentation put online
To-do high priority¶
- Add ADI (including PCA) of total intensity images for pupil-tracking observations
- Change config file option skip_preprocessing to perform_preprocessing: True/False, perform_polarimetry: True/False and perform_adi: True/False
- Add option to express final images in contrast/arcsec^2 or mJansky/arcsec^2
- Add plot of center coordinates of center frames vs time
- Test polarimetric data with dithering applied (e.g. centering methods, subtraction of object file from center file)
- Add accurate (calibrated) model correction for narrowband filters
- Add option to apply accurate plate scale and distortion correction for data (especially important for pupil-tracking and bright sources; do we need calibrations?)
- Add detection limits (e.g. contrast curves)
To-do low priority¶
- Add images and plots aimed at analysis of polarimetric data (R^2 scaling, AoLP arrows in polarized intensity or DoLP images, contrast curves etc.)
- Add option to subtract DARK,BACKGROUND-frames if sky files are lacking (especially important for Ks; test effect first before completely implementing)
- Add option for ‘stupid ADI’ for field-tracking data with derotator offset and option to subtract 180 deg rotated image if no derotator offset
- Add warning if (part of the) data is taken at a low polarimetric efficiency, and perhaps make plot of efficiency vs file number
- Add optional ADI (including PCA) for polarization images
- Make figures with sub-images horizontal, or make multiple lines of left and right images in a single figure
- Add options for various methods to shift and rotate images (interpolate, ndimage-fourier, sci-image functions; similar to VIP)
- When rotating images, make complete frame still visible to not cut out any parts of the data
- Improve centering of non-coronagraphic data (center found depends a lot on first PSF and affects Qphi and Uphi images)
- Test finding of satellite spots of center files when waffle pattern is ‘+’
- Add weighted least-squares as option for model correction (depending on image quality or polarimetric efficiency)
- Add multiprocessing for sigma filtering and centering of frames
- Make IRDAP runable from a script by importing it and calling main function
- Add option to scale the master sky frame to subtract from the object frames (especially for Ks; see also Gallicher et al. 2011)
- Exclude saturated pixels in aperture to determine star polarization (same way as used in function fit_2d_gaussian)
- Determine star polarization as a function of aperture radius
- Add optional RDI for total intensity images
- Make docstrings compliant with accepted conventions and create API doc on website
