VISIT-STIS-Coron

VISIbility Tool for HST/STIS Coronagraph (VISIT-STIS-Coron), version 0.1. Developed by Bin Ren (Caltech) as a Phase II preparation tool for HST/STIS coronagraph.

TLDR: Check out VISIT-STIS-Coron Demo.ipynb for usage demo.

Some advantages of VISIT-STIS-Coron:

1. This tool uses a physical mask created by John H. Debes (STScI) in Debes et al. (2017).
2. The coronagraphic occulting locations (BAR5, BAR10, WEDGEA0.6, WEDGEA1.0, WEDGEA1.8, WEDGEA2.0, WEDGEA2.5, WEDGEA2.8, WEDGEB1.0, WEDGEB1.8, WEDGEB2.0, WEDGEB2.5, WEDGEB2.8), as well as POSTARG parameters, are supported. See STIS_coron_positions.pdf for their actual locations.
3. Most accurate occluting locations and diffration spikes. The occulting locations are measured by Bin Ren (Caltech) previously presented in Ren et al. (2017). The diffraction spikes are also measured to be 10-pixel wide.
4. Support for the ORIENT parameter used in Phase II preparation.
5. If you position your target outside the occulting locations using POSTARG parameters, a warning message will be printed.

Acknowledgements:

1. I thank John H. Debes for allowing me to make the mask file he created in Debes et al. (2017) public. If you use that FITS file in your research, please cite Debes et al. (2017).
2. I thank Kimberly Ward-Duong for developing STIS Coronagraphic Visualization Tool (Preliminary Release) which I used to verify the parameter setup for VISIT-STIS-Coron.

To be done: Overall representation/choice of colormap, markers, etc.
