Photometry

Spitzer

• Kirkpatrick et al. (2012): [3.6]=16.92 (0.02), [4.5]=14.32 (0.02)
• Beichman et al. (2013): [3.6]=17.17 (0.03), <[4.5]>=14.55 (0.03)
• Beichman et al. (2014): [3.6]=16.88 (0.05), [4.5]=14.30 (0.03)
• Leggett et al. (2013): [3.6]=16.84 (0.01), [4.5]=14.27. (0.01) [derived from archived data for GO program 70062 and DDT program 551. A 30 mmag (3%) error should be added in quadrature to the quoted random errors for the IRAC data to account for systematics.]
