Variation in the measured [OIII]5007/[OIII]4959 flux ratio. #196
Comments
Thanks for the report @dirkscholte. @jdbuhler would you be willing to take a look at this issue? I've verified that the Note that because of the resolution matrix convolution we expect the However, since the line-width I think the issue is here, where we render the (model) line-profile for each line: This is the line-profile we integrate to compute the (Gaussian) flux, but I think we need the line-profile without the resolution matrix: |

@moustakas @jdbuhler I am just adding another figure that John suggested to make. Here still showing the [OIII]5007/[OIII]4959 ratio but now with |

I found that for some low redshift galaxies the measured [OIII]5007/[OIII]4959 ratio deviates from the theoretical ratio by a small fraction.
The deviation can be seen for a small sample of high S/N [OIII]
