Why does "early-type" have a hyphen in some places but not in others? Shouldn't this be consistent?
Compound terms such as "early type," "V band," and "intermediate redshift" are hyphenated when they are used as adjectives (as in "many early-type stars were seen in intermediate-redshift V-band observations") but open as nouns ("we find many early types at intermediate redshifts in the V band"), following conventional English style for compound nouns and adjectives.
