A Distance Measurement to M33 Using Optical Photometry of Mira Variables

We present a systematic analysis to determine and improve the pulsation periods of 1637 known long-period Mira variables in M33 using gri -band light curves spanning ∼18 yr from several surveys, including the M33 variability survey, Panoramic Survey Telescope and Rapid Response System, Palomar Trans...
