Recovered fluorescence lifetime parameters for 5A and Myr5A in different solvents

τ is lifetime in nanoseconds; τInt and τAmp are average intensity-weighted and amplitude-weighted lifetimes in nanoseconds, respectively; A is an amplitude in percentage for respective lifetime components; χ2 is χ2 for goodness of fit.
