VizieR Online Data Catalog: BVRI, spectra & IR obs. of type II-P SN2017eaw (Van Dyk+, 2019)

Multiband BVRI images of SN 2017eaw were obtained with both the Katzman Automatic Imaging Telescope (KAIT) and the 1m Nickel telescope at Lick Observatory. Unfiltered images were also obtained with KAIT. We also obtained near-daily BVRI coverage with the pt5m, a 0.5m robotic telescope at the Roque de los Muchachos Observatory, La Palma. Exposure times for these observations were 5x15s for both B and I, and 5x10s for both V and R, prior to 2017 October 26. From that date onward, exposure times were 5x45s for both B and I, and 5x40s for both V and R. See Table 1, Fig 2 (and Section 2.1).

Over an eight-month period beginning on 2017 May 19, a series of 20 optical spectra of SN 2017eaw were obtained with the Kast double spectrograph mounted on the 3m Shane telescope at Lick Observatory. With the Blue Channel (BC) spectrograph on the MMT we also obtained nine spectra with the 1200lines/mm grating, with a central wavelength of 6360Å and a 1.0" slit width, and two spectra with the 300lines/mm grating. We also obtained five epochs of optical spectroscopy with the Boller & Chivens (B&C) spectrograph mounted on the 2.3m Bok telescope on Kitt Peak. See Fig 3. Additionally, some of us (H.I., I.J.M.C., D.H., M.R.K.) obtained an optical spectrum of SN 2017eaw with the HIRES spectrometer on the KeckI 10m telescope on Maunakea on 2017 June 2. See Table 2 and Section 2.2.

The site of SN 2017eaw was observed serendipitously by several HST programs prior to explosion. These include GO-14156 (PI A. Leroy) with the Wide Field Camera 3 (WFC3) IR channel in bands F110W (total exposure 455.87s) and F128N (1411.74s) on 2016 February 9, and GO-14638 (PI K. Long) with WFC3/IR F160W (396.93s) on 2016 October 24; and GO-9788 (PI L. Ho) with the Advanced Camera for Surveys (ACS) Wide Field Channel (WFC) on 2004 July 29 in F658N (700s) and F814W (120s), and GO-14786 (PI B. Williams) with ACS/WFC on 2016 October 26 in F814W (2570s) and F606W (2430s).

The SN site was also serendipitously observed pre-explosion by a number of programs on various dates, from 2004 June 10 to 2017 March 31, using Spitzer. We list all of these observations and the data that we considered in Table 3. See Sections 2.4 and 7.2.

Finally, we observed SN 2017eaw on 2017 May 29.79 with HST WFC3/UVIS in subarray mode in F814W (270s total exposure), as part of our Target of Opportunity (ToO) program (GO-14645, PI S. Van Dyk). See Section 2.5.
