    Louis, R. E; Ravindra, B; Mathew, S. K; Bellot Rubio, L. R; Bayanna, A. R; Venkatakrishnan, P (IOP Publishing, 2012-08-10)
    We employ high-resolution filtergrams and polarimetric measurements from Hinode to follow the evolution of a sunspot for eight days starting on 2007 June 28. The imaging data were corrected for intensity gradients, projection ...
  • Properties of umbral dots from stray light corrected hinode filtergrams 
    Louis, R. E; Mathew, S. K; Bellot Rubio, L. R; Kiyoshi, I; Ravindra, B; Raja Bayanna, A (IOP Publishing, 2012-06-20)
    High-resolution blue continuum filtergrams from Hinode are employed to study the umbral fine structure of a regular unipolar sunspot. The removal of scattered light from the images increases the rms contrast by a factor ...
