VizieR Online Data Catalog: i filter photometry for HATS-25 through HATS-30 (Espinoza+, 2016)

The photometric detection data of the six exoplanets come from the three HATSouth sites, namely, the site at Las Campanas Observatory in Chile (LCO, whose stations are designated HS-1 and HS-2), the site at of the High Energy Spectroscopic Survey (HESS) in Namibia (whose stations are designated HS-3 and HS-4) and the site at the Siding Spring Observatory (SSO) in Australia whose stations are designated HS-5 and HS-6).

HATS-25 was observed with an r SDSS filter on 2011 Mar-2011 Aug using HS-2.1, on 2011 Jul-2011 Aug using HS-4.1, and on 2011 May with HS-6.1. HATS-26 was observed with an r SDSS filter on 2012 Feb-2012 Jun using HS-2.3, HS-4.3, and HS-6.3. HATS-27 was observed with an r SDSS filter on 2011 Apr-2012 Jul using HS-2.1, on 2011 Jul-2012 Jul using HS-4.1, and on 2011 May-2012 Jul using HS-6.1. HATS-28 was observed with an r SDSS filter on 2013 Mar-2013 Oct using HS-1.2, on 2013 Sep-2013 Oct using HS-2.2, on 2013 Apr-2013 Nov using HS-3.2, on 2013 Sep-2013 Nov using HS-4.2 and HS-6.2, and 2013 Mar-2013 Nov using HS-5.2. HATS-29 was observed with an r SDSS filter on 2013 Apr-2013 May using HS-1.1, on 2013 Sep-2013 Oct using HS-2.1, on 2013 Apr-2013 Nov using HS-3.1, on 2013 Sep-2013 Nov using HS-4.1 and HS-6.1, and on 2013 Mar-2013 Nov using HS-5.1. HATS-30 was observed using an r SDSS filter on 2012 Sep-2012 Dec using HS-2.3, HS-6.3 and HS-2.4, on 2012 Sep-2013 Jan using HS-4.4, on 2012 Sep-2012 Dec using HS-6.4, and on 2011 Jul-2012 Oct using HS-1.1, HS-3.1 and HS-5.1.

Photometric follow-up for the six systems was obtained mainly from 1m-class telescopes at different sites of the Las Cumbres Observatory Global Telescope (LCOGT) network, using the i filter. In particular, one partial transit and a full transit was observed for HATS-25b on 2015 February 23 at Cerro Tololo Inter-American Observatory (CTIO) and 2015 March 16 at SSO, respectively; three partial transits were observed for HATS-26b on 2015 April 19 and 2015 May 21 at CTIO, and 2015 June 04 at SSO; one full transit was observed for HATS-27b on 2015 April 09 at SSO; two partial transits were observed for HATS-28b on 2015 August 31 and 2015 September 03 at CTIO; one full transit and a partial transit were observed for HATS-29b on 2015 and 2014 June, respectively, at CTIO; and two partial transits were observed for HATS-30b on 2014 October 19 at South African Astronomical Observatory (SAAO) and on 2014 Oct 23 at CTIO. In addition, one full transit of HATS-27b was observed using the 0.3m Perth Exoplanet Survey Telescope (PEST) on 2015 March 12 using a R_C filter.

The reconnaissance spectroscopy of our candidates was made using the Wide Field Spectrograph (WiFeS), located on the Australian National University (ANU) 2.3m telescope. The observing strategy usually consists of taking data with two resolutions: R=λ/Δλ=7000 (medium) and R=3000 (low). For HATS-25, four medium resolution spectra (2014 Jun-Aug) and one low resolution spectrum (2014 Aug 5) were obtained. For HATS-26, two medium resolution spectra (2014 Jun 3-5) and one low resolution spectrum (2014 Jun 4) were obtained. For HATS-27, three medium resolution (2014 Jun 3-5) and one low resolution (2014 Jun 2) spectra were obtained. For HATS-28, only one low resolution spectrum (2015 Jun 1) was obtained. For HATS-29, four medium resolution spectra (2014 Dec-2015 Mar) and one low resolution spectrum (2015 Mar 2) were obtained. For HATS-30, three medium resolution spectra (2014 Oct 4-10) and one low resolution spectrum (2014 Oct 4) were obtained.

High-precision spectroscopy was obtained for our targets with different instruments. Several R=115000 spectra were taken with the High Accuracy Radial Velocity Planet Searcher (HARPS) on the ESO 3.6m telescope at La Silla Observatory (LSO) between 2015 February and 2016 March in order to obtain high-precision radial velocities for HATS-25, HATS-26, HATS-27, and HATS-29. Spectra with R=48000 were also taken with the Fiber-fed Extended Range Optical Spectrograph (FEROS) mounted on the Max Planck Gesellschaft (MPG) 2.2m telescope at La Silla Observatory (LSO) between 2014 July and 2015 July in order to both extract precise spectroscopic parameters of the host stars and obtain precise radial velocities for all of our targets. In addition, R=60000 spectra were also taken with the CORALIE spectrograph mounted on the 1.2m Euler telescope at LSO between 2014 June and November for HATS-26, HATS-27, HATS-29, and HATS-30. Finally, eight R=70000 spectra were obtained for HATS-29 on 2015 May to measure radial velocities, using the CYCLOPS2 fiber feed with the University College London Echelle Spectrograph (UCLES) on the 3.9m Anglo-Australian Telescope (AAT).
