Abstract:
We obtained long-slit optical spectroscopy of one transit of WASP-48b
with the Optical System for Imaging and low-Intermediate-Resolution
Integrated Spectroscopy (OSIRIS) spectrograph. We report a relatively
flat transmission spectrum (wavelength coverage from 530 nm to 905 nm)
for WASP-48b with no statistical significant detection of atmospheric
species, although the theoretical models that fit the data more
closely include TiO and VO.
Description:
We present the white light curve and the curves produced using bins of
25nm in width, and bins of 10nm in width of one full transit event of
WASP-48b taken on July 17, 2014. We provide auxiliary parameters of
the observations that were used to detrend the original light curves.
These parameters are: airmass, FWHM of the spectral profile in spatial
direction, and telescope rotator angle.
