Low-degree low-order solar p modes as seen by GOLF on board SOHO

Data recovered from the GOLF experiment on board the ESA/NASA SOHO spacecra ft have been used to analyze the low-order low-degree solar velocity acoust ic-mode spectrum below v = 1.5 mHz (i.e., 1 less than or equal to n less th an or equal to 9 ,l less than or equal to 2). Various techniques (periodogr am, RLAvCS, homomorphic-deconvolution and RLSCSA) have been used and compar ed to avoid possible biases due to a given analysis method. In this work, t he acoustic resonance modes sensitive to the solar central region are studi ed. Comparing results from the different analysis techniques, 10 modes belo w 1.5 mHz have been identified.
