Analysis pipeline for HST/WFC3 spectroscopic observations of exoplanet transits and eclipses
A complete package to analyse single-object spatially scanned spectroscopic observations of extrasolar planets obtained with the near-infrared grisms (G102, G141) of the Wide Field Camera 3 on-board the Hubble Space Telescope.
- Reduction of the raw frames.
- Calibration of the position of the total spectrum and the different spectral elements.
- Extraction of the total flux and the flux per spectral element.
- Fitting of the white and the spectral light-curves.
Currently, fitting can be applied only on single-visit light-curves but in the next version it will be updated to fit also multiple visits of the same target simultaneously.
