WFC3: Spatially-scanned Spectra of Exoplanet Transits (and more)! ... 2011). ... This work confirms that the transit spectrum of GJ 1214b is both flat and featureless. ... Scaling from the demonstrated performances of WFC3 on GJ 1214b (Berta et al's work and this work), and aiming for a 50% duty cycle of observation, we predict that in a single transit of HD 97658b we should be able to collect 80 times more photons than the total number of photons in 3 transits of GJ 1214b observed by Berta et al. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... MARX includes models of the AXAF mirrors, the low- and high-energy transmission grating assemblies (LETG and HETG), and the HRC and ACIS focal plane detectors. We discuss the role of MARX within the ASC Data System and present sample simulated images and spectra for two typical cosmic X-ray sources. ... A continuous emission measure model was constructed based on the published EUVE data (Dupree 1996); the peak emission occurred near 10 7 K. Simulations were run for both the HETG and LETG . ...
