Receipt: # 15429-2 ----- Attempting Submission 3 (Mon Dec 11 21:57:33 GMT 2017) ----- The warning regarding lack of fringe flats is incorrect: Each visit has multiple fringe flats during visibility and occultation. The warning appears to be triggered because these flats are of nonstandard setup/duration, exceeding the default duration by up to a factor of 2. Is C60+ present in the diffuse interstellar medium? New innovations in laboratory spectroscopy at ultra-low temperatures have provided strong evidence for the presence of C60+ (ionized Buckminsterfullerene) in the diffuse interstellar medium (ISM). If confirmed, this discovery would provide a major breakthrough in interstellar chemistry and a potential resolution for the 100-year old diffuse interstellar band (DIB) problem. Although Walker et al. (2015, 2016) claimed its detection, the presence of a crucial absorption band of C60+ at 9428 A was called into question this summer when new spectra were presented by Galazutdinov et al. (2017). Confirming the presence of C60+ now rests on a rigorous detection of this 'missing' 9428 A band, but this region of the spectrum is heavily contaminated in ground-based studies due to strong telluric water vapour absorption. Use of HST is urgently required to obtain robust near-IR interstellar spectra, eliminating the need for error-prone telluric cancellation methods and thus allowing us to definitively confirm or reject the presence of interstellar C60+. The target stars will be acquired at the center of the 52x0.1'' slit (at row 512) then moved to CCD row 300 for the start of the STIS-scan routine. The targets will be exposed while scanning up the slit by 36'' to row 1000 (at a rate not exceeding the maximal FGS tracking rate of 4.8''/sec). After readout, the star will be repositioned at row 300 and a second identical science exposure will be performed. Next, a sequence of two contemporaneous flat-field exposures will be obtained (without moving the slit mechanism), to ensure the closest alignment between the flat and science exposures. This exposure sequence will be repeated one to two more times depending on the amount of remaining time in the orbit. Additional wavecal and fringe flats will be obtained during occultation to improve the flat-field statistics and accuracy of the wavelength scale. The exposure times are set to reach target S/N > 500 per exposure, so that the sequence of >4 science exposures will result in total counts equivalent to S/N > 900 (allowing for ~10% flux losses due to scattered light not accounted for by the ETC). Individual exposure times can exceed the nominal pixel saturation limit given by the ETC because the counts will be spread over 700 (spatial) rows (instead of the 7 assumed by the ETC).
