Abstract:
    This paper reports results of the third-year campaign of monitoring
    super-Eddington accreting massive black holes (SEAMBHs) in active
    galactic nuclei (AGNs) between 2014 and 2015. Ten new targets were
    selected from the quasar sample of the Sloan Digital Sky Survey
    (SDSS), which have generally been more luminous than the SEAMBH
    candidates in the last two years. Hβ lags (τHβ) in
    five of the 10 quasars have been successfully measured in this
    monitoring season. We find that the lags are generally shorter, by
    large factors, than those of objects with same optical luminosity, in
    light of the well-known RHβ-L5100 relation. The five quasars
    have dimensionless accretion rates of dM/dt=10-103. Combining these
    with measurements of the previous SEAMBHs, we find that the reduction
    of Hβ lags depends tightly on accretion rates,
    τHβ/τR-L∝(dM/dt)-0.42, where τR-L is
    the Hβ lag from the normal RHβ-L5100 relation. Fitting
    63 mapped AGNs, we present a new scaling relation for the broad-line
    region: RHβ=α1l44β1min
    [1,(dM/dt)/(dM/dt)c)-γ1], where l44=L5100/1044erg/s is
    the 5100Å continuum luminosity, and the coefficients are
    α1=29.6-2.8+2.7 lt-day, β1=0.56-0.03+0.03,
    γ1=0.52-0.16+0.33, and (dM/dt)c=11.19-6.22+2.29. This
    relation is applicable to AGNs over a wide range of accretion rates,
    from 10-3 to 103. Implications of this new relation are briefly
    discussed.
Description:
    The super-Eddington accreting massive black hole (SEAMBH) project uses
    the Lijiang 2.4m telescope, operated by Yunnan Observatories. We
    adopted the same observational procedures described in detail in
    PaperI (Du et al. 2014, J/ApJ/782/45). Observational results of the
    three years spectroscopic monitoring (2012-2014) are listed in table1.

Note (1): We marked the time lag of J080131 as "uncertain" in Paper IV
          (Du+, 2015, J/ApJ/806/22), but we pick it up here because its lag
          reported in Paper IV is highly consistent with the number measured
          in the present paper.

Note (2):
  b = MCG+06-26-012 was selected as a super-Eddington candidate in SEAMBH2012
      but was later identified to be a sub-Eddington accretor (dM/dt=0.46);
      we discard it here (no Hβ reverberations data for this object).

Note (G1): Phase as follows:
   1 = First phase: SEAMBH2012 sample
   2 = Second phase: SEAMBH2013 sample
   3 = Third phase: SEAMBH2014 sample
