<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'coeff_mf.txt and error_coeff_mf.txt have the Legendre fitting coefficients and the fitting uncertainties respectively for the corrected baseline meridional flow on the same latitude-time grid as Level 3 flow profiles. Similar coefficients for solar rotation rate are in coeff_dr.txt and error_coeff_dr.txt. The rotation rate is in Carrington frame of reference. Unit: m/s.These are the coefficients of associated Legendre polynomials with order 1 and degrees 1 to 6 calculated as a function of time. The associated Legendre Polynomials are:x   = sind(info.lat(:,1));x2 = cosd(info.lat(:,1));p1 = x2;p2 = 2*x.*x2;p3 = .726*(5*x.^2-1).*x2 ;p4 = 1*(7*x.^3-3*x).*x2 ;p5 = .583*(21*x.^4-14*x.^2 +1).*x2 ;p6 = .842*(33*x.^5 - 30*x.^3 + 5*x).*x2 ' .
