Notes. m_B and m_V (Cols. 2 and 4) are the apparent magnitudes at maximum in the B and V bands, and s_BV (Col. 6) is the stretch color parameter (Col. 7). The color m_B − m_V (Col. 8) is computed as the difference between the maximum brightness in B and V bands, and M_B (Col. 9) is the absolute magnitude in B band, computed as m_B − μ_SBF, where μ_SBF is taken from Table 1.
