Under the copied image of the 4 objects, for each corresponding object (label a heading in your report Virgo Cluster through the Bootes Cluster and under each heading you'll have information for questions #1 - #4, also labeled.) For #1, type out the numbers you estimate for each Balmer hydrogen line (H-alpha, H-beta, etc.) in each galaxy spectra given (match the line pattern as it is labeled on the spectrum of the Virgo cluster galaxy). So for example: Virgo Cluster # 1: H-alpha = 660nm, H-beta = xxx, etc. doing the same for each line and for each object.
