VizieR Online Data Catalog: Helioseismic measurements of solar meridional flow (Liang+, 2018)
Abstract
The measured travel-time shifts are averaged over three periods, cycle 23 (May 1996 to April 2008; 3051 days used), cycle 24 (May 2008 to April 2017; 2833 days used), and both the cycles 23 and 24 (May 1996 to April 2017; 5884 days used), as a function of latitude and travel distance. Also provided are the standard errors of the temporal means over the three periods. They are all in units of seconds. The coordinates of these maps can be obtained from the WCS keywords in the headers; that is, latitude = (i - CRPIX1)*CDELT1 + CRVAL1 [deg], and distance = (j - CRPIX2)*CDELT2 + CRVAL2 [deg], where i=1..200 and j=1..61.
