VizieR Online Data Catalog: HST obs. of Mira variables in the SNIa host NGC1559 (Huang+, 2020)

This study uses 10 epochs of HST WFC3/IR F160W data (GO-15145; PI Riess), with an exposure time of 1006s for each epoch. The epochs have an approximately monthly cadence between 2017 September 8 and 2018 September 11, with a field of view centered at RAJ2000=04:17:37 and DEJ2000=-62:47:00.

To put our observations on the same zero-point as H18 (Huang+, 2018, J/ApJ/857/67), which we adopt for an absolute calibration of distance, we use the same HST WFC3 IR photometric zero-point for a 0.4"-radius aperture. In Vega magnitudes, the F160W zero-point is 24.5037mag. See Section 2.2.
