=====================================================================================================================

At present several thousand transiting exoplanet systems have been discovered.
For relatively few systems, however, a spectro-photometric characterization of
the planetary atmospheres could be performed due to the tiny photometric
signatures of the atmospheres and the large systematic noise introduced by the
used instruments or the earth atmosphere. Several methods have been developed to
deal with instrument and atmospheric noise. These methods include high precision
calibration and modeling of the instruments, modeling of the noise using methods
like principle component analysis or Gaussian processes and the simultaneous
observations of many reference stars. Though significant progress has been made,
most of these methods have drawbacks as they either have to make too many
assumptions or do not fully utilize all information available in the data to
negate the noise terms.

The :blue:`CASCADe` package, developed within the EC Horizons 2020 project
:red:`Exoplanets A`, implements a full spectroscopic pipeline for HST/WFC3 and
Spitzer/IRS spectroscopic timeseries observations as well as lightcurve
calibration and fitting functionality. The :blue:`CASCADe` project implements a
novel “data driven” method, pioneered by Schoelkopf et al (2016) utilizing the
causal connections within a data set, and uses this to calibrate the spectral
timeseries data of a transiting systems, observed in a single object mode.
The current code has been tested successfully on spectroscopic data obtained
with the Spitzer and HST observatories, as well as JWST MIRI simulations.
