Comparison of extracted Hα fluxes, Hβ fluxes and estimated errors for the Hα line of NGC 5614, as extracted by Gandalf using the MILES stellar template library, the SSP library and a Monte Carlo variation of noise in the spectra. There is a very good match in the line fluxes between the three methods for the Hα line (row 1), while the errors estimated by Gandalf are larger than the statistical variance from the Monte Carlo approach (row 3). The weak Hβ line is generally better recovered using either the Monte-Carlo or GANDALF/SSP method (row 2).
