Visits 05 and 06 were created to replace Visit 01 and Visit 03 and impliment a switch from the Nicmos instrument to the WFC3/IR. The POS TARG of (-15.173, 1.158) is intended to place the first order spectrum within the 128x128 sub-array as defined in the 2010 WFC3 Technical report "IR Grism Subarray Design and Use". The fiducial pixel is at (410, 532) located ouside the 128x128 subarray, but within the 256x256 subarray used for the direct filter image. This POS TARG of (-15.173, 1.158) was entered into each exposure. The special requirement New Obset was added to the start of Orbits 2, 3, and 4. Visit Orientation Requirements are set such that the faint nearby companion to HD189733 (located 10.2" west and 4.6" south) does not have overlapping spectra with the target. The Position angle of the compantion (HD189733B) is at 245.726 degees, which should not be oriented with the +/- X-axis of the detector by +28 degrees or -45 degrees. ----- Attempting Submission 1 (Tue Jun 17 12:53:56 GMT 2008) ----- ----- Attempting Submission 2 (Fri Jun 05 11:34:38 GMT 2009) ----- ----- Attempting Submission 3 (Tue Jun 29 15:12:02 GMT 2010) ----- HST Phase II Proposal 11740 (WFC3_HD189.apt) successfully submitted. ----- Attempting Submission 4 (Wed Jun 30 08:55:27 GMT 2010) ----- HST Phase II Proposal 11740 (WFC3_HD189.apt) successfully submitted. ----- Attempting Submission 5 (Wed Jun 30 08:58:19 GMT 2010) ----- The "Program Coordinator Box" is now checked.

Here we propose STIS and Nicmos spectra to help construct a full exoplanetary transit transmission spectrum that extends over the entire optical and near-infrared range. Such a spectrum will link existing observed atmospheric features such as haze, water, and methane, providing a coherent understanding of all these reported features. With a spectrum covering many observed absorption features, the absolute pressure scale and abundances can be determined linking observed features to the actual atmospheric properties of the exoplanet.
For both NICMOS/G141 and STIS/G430L two transits of HD 189733 will be observed. Each of these 4 HST visits will consist of 4 HST orbits, with orbit 3 roughly centered on the planet transit, and orbits 2 and 4 outside of transit to establish the baseline. The first orbit is assumed not to be useful (instrument settling). With NICMOS HD 189733 is x2.04 brighter in H-band than the previously observed HD 209458 and GJ436. With HD 209458 and GJ436 (GO-9832, 11306) STEP1, NSAMP=4 with 1.996 s exposures was adopted, and moderate defocus (now adopted as the standard defocus for this type of work, e.g. see more recent NICMOS program 11306). For the brighter HD 189733 STEP1, NSAMP=3 will yield 0.995 s exposures and almost exactly the same exposure level. The first NICMOS orbit will include a direct image in F166N for wavelength specification, then as many 0.995 s exposures as possible will be obtained in the remaining time with G141. The G141 integrations should peak at less than 90,000 e-/s providing an excellent linearity correction. Photon-noise limited precisions should be 0.00016 per resoluton element per HST orbit. With STIS G430L the wavelength range of 2900-5700 angstroms is covered. We use a broad 52x2" slit to minimize slit losses and variations. STIS is perfectly conserving past saturation with use of GAIN=4, see e.g. Bohlin and Gilliland 2004, AJ, 127, 3508 describing observations of the 0th mag star Vega. We adopt an exposure time of 66 seconds, with a sub-array size of 128 -- sufficiently large to enable tracking sky variations. This will lead to roughly 2x oversaturation. Photon-limited precisions of 0.00017 per resolution element, per HST orbit are expected. During the first orbit of STIS use exposure times of 66 and 64 seconds are interchanged to provide verification of linearity at the transit depth. Similar changes of integration time are not included in the first NICMOS orbit since two previous trials showed near perfect linearity correction is already obtained. The NICMOS orbits out-of-transit use nominal, +0.05 pixel (0.01 arcsec), -0.05 pixel, and nominal dithers to help provide well-posed decorrelation data for expected instrumental drifts. Implementation notes: the relatively new parameter CAMERA-FOCUS=DEFOCUS and aperture NIC3-FIXD is used to place the NIC3 focus mechanism at -0.5mm and adjust the target placement in the aperture for the defocus respectively.
