We demonstrate this with mixtures in the lowest two (1-2), and second lowest two (2-3) hyperfine states. For the 1-2 mixture, we can achieve condensate fractions of 36\\%, with $9\\times10^4$ atoms at $0.05\\textrm{ }\\mu\\textrm{K}$ temperature. For the 2-3 mixture, we have 28\\% condensed with $3.2\\times10^4$ atoms at $0.05\\textrm{ }\\mu\\textrm{K}$ temperature. We use mostly standard methods, but make a number of refinements in the magnetic bias coils compared with earlier work.
