VizieR Online Data Catalog: HST obs. of Mira candidates in NGC 4258 (Huang+, 2018)
Abstract
With a roughly monthly observational cadence, we used 12 epochs of HST WFC3 data (GO 13445; PI: Bloom) collected between 2013 October 2 and 2014 August 3 to search for Miras in NGC 4258. All 12 epochs have F160W and F125W data. The observations were centered at RAJ2000=12:18:52.800 and DEJ2000=+47:20:19.70. This field was previously observed in F160W (GO 11570; PI: Riess) in 2009 December and 2010 May. These earlier images were taken to create a mosaic of NGC 4258 in F160W.
This field was previously observed at optical wavelengths using HST (GO 9810; PI: Greenhill Macri+ 2006, J/ApJ/652/1133). These observations were taken with the Advanced Camera for Surveys (ACS) in F435W, F555W, and F814W. The optical time-series consisted of 12 epochs between 2003 December 5 and 2004 January 19.
