Bean et al. 2011 spec Magellan II Landon Clay TelescopeMMIRS36BEAN ET AL 2011 MMIRS We used an HK grism as the dispersive element and an HK filter to isolate the first-order spectra. Complete spectra from 1.23 to 2.48m with a dispersion of 6.6 were obtained for all the objects
Berta et al. 2012 spec Hubble Space Telescope satelliteWFC324BERTA ET AL 2012 WFC3 We observed three transits of GJ1214b on UT 2010 October 8, 2011 March 28, and 2011 July 23 with the G141grism on WFC3 infrared channel (HSTProposal GO-12251,PI: Z.

Croll et al. 2011 phot Canada-France-Hawaii TelescopeWIRCam8CROLL ET AL 2011 : We observed the transit of GJ 1214b on four occasions with WIRCam on CFHT. For each transit we observed GJ 1214 in two bands nearly simultaneously by rapidly switching the WIRCam filter wheel back and forth between the two filters. We observed GJ 1214 alternating between the J (1.25 microns) and Ks (2.15microns) filters on the evenings of 2010 June 27, 2010 August 15 and 2010 September 22. On the evening of 2010 August 7 we observed GJ 1214 alternating between the Jand CH4On filters (1.69 microns)

A narrow-band (1%) filter centered on 2.14 was used.

de Mooij et al. 2012 phot Isaac Newton Groups William Herschel TelescopeLIRIS1DE MOOIJ ET AL 2012 : The Kc-band (2.27) observations were obtained with the Long-slit Intermediate Resolution Infrared Spectrograph (LIRIS; Acosta-Pulido et al. 2002) on the William Herschel Telescope (WHT) on the night of August17, 2010. The pixel-scale of the LIRIS detector is 0.2''/pixel, resulting in a field of view of the detector of 4.2 by 4.2 arcminutes. The same reference stars as for the NOTCam observations were used.
de Mooij et al. 2012 phot Max Planck Gesellschaft 2.2 meter Telescope at European Southern ObservatoryGROND4DE MOOIJ ET AL 2012 : On the night of July 3, 2010, we obtained simultaneous observations of GJ1214b in the g (459 nm), r (622 nm), i (764 nm), and z-band (899 nm) with the GROND instrument (Greiner et al. 2008) on the 2.2 meter MPI/ESO telescope at La Silla in Chile. The field of view in each of the wavelength channels is 5.4' by 5.4', which is sufficient to observe both GJ1214 and a set of reference stars simultaneously.The observations started at 00:16 UT and lasted until 04:06 UT. During this time we obtained 280 frames in each of the four optical bands. The exposure time was varied from 20 to 30 seconds to avoid saturation of the CCDs. The average cycle time was 50 seconds.

Désert et al. 2011 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)2DESERT ET AL 2011 : We report observations of two consecutive transits of the warm super-Earth exoplanet GJ 1214b at 3.6 and 4.5 microns with the Infrared Array Camera instrument on-board the Spitzer Space Telescope. The two transit light curves allow for the determination of the transit parameters for this system. We find these paremetersto be consistent with the previously determined values and no evidence for transit timing variations. The main investigation consists of measuring the transit depths in each bandpass to constrain the planet's transmission spectrum.
Gillon et al. 2014 phot La Silla Observatorys 60-cm TRAPPIST TelescopeTRAPPISTCam1GILLON ET AL 2014: In 2011, we observed seven transits of GJ 1214 b from Chile with the 60 cm robotic telescope TRAPPIST located at ESO La Silla Observatory. We monitored all the transits with the telescope slightly defocused and in the I+z filter that has a transmittance > 90 % from 750 nm to beyond 1100 nm.

Kreidberg et al. 2014 spec Hubble Space Telescope satelliteWide Field Camera 322KREIDBERG ET AL 2014 We obtained time-series spectroscopy from 1.1 to 1.7 m during each observation. The data were taken in spatial scanmode, which slews the telescope during the exposure and moves the spectrum perpendicular to the dispersion direction on the detector. The observations had the following design. At the beginning of each orbit, we took a direct image with the F130N narrowband filter to establish a wavelength zero-point. For the remainder of each orbit, we took spatially scanned exposures with the G141 grism.

Rackham et al. 2017 spec Magellan I Walter Baade TelescopeIMACS spectrograph14RACKMAN ET AL IMACS Details for the three transit observations are provided in Table1. We carried out all observations in spectroscopic mode with no filter. We observed two transits with the f/4 camera and one with the f/2 camera; therefore we designed two with three criteria:(1)to include the widest spectral range for the target and comparison stars,(2)to include as many comparison stars as possible, and(3)to eliminate slit losses using extra-wide slits. We also used larger lengths for the slits in order to adequately sample the sky background
