Todo
- (!) Replace static flat in Ks by one with P0-90 inserted
- (!) Combine data of different OB’s with automatic selection of correct center, sky and flux images
- (!) 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 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 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
- (?) 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
- v0.1.2 June 2019, R.G. van Holstein:
- Release of IRDAP package on PyPI and GitHub
- Documentation put online
