<jats:title>ABSTRACT</jats:title>
<jats:p>We present a high-precision measurement of the parallax for the 12-day Cepheid SS Canis Majoris, obtained via spatial scanning with the Wide Field Camera 3 (WFC3) on the <jats:italic>Hubble Space Telescope (HST)</jats:italic>. Spatial scanning enables astrometric measurements with a precision of 20–40 <jats:italic>μ</jats:italic>as, an order of magnitude better than pointed observations. SS CMa is the second Cepheid targeted for parallax measurement with <jats:italic>HST</jats:italic> and is the first of a sample of 18 long-period (≳10 days) Cepheids selected in order to improve the calibration of their period–luminosity relation and eventually permit a determination of the Hubble constant <jats:italic>H</jats:italic>
<jats:sub>0</jats:sub> to better than 2%. The parallax of SS CMa is found to be 348 ± 38 <jats:italic>μ</jats:italic>as, corresponding to a distance of 2.9 ± 0.3 kpc. We also present a refinement of the static geometric distortion of WFC3 obtained using spatial scanning observations of calibration fields, with a typical magnitude ≲0.01 pixels on scales of 100 pixels.</jats:p> |
