Photometry

Spitzer

• Kirkpatrick et al. (2012): [3.6]=16.88 (0.05), [4.5] = 14.06 (0.02)
• Leggett et al. (2013): [3.6]=16.78 (0.01), [4.5]=14.02. (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.]
• Schneider et al. (2015):[3.6]=16.876 (0.046), [4.5]=14.058 (0.019)
• Martin et al. (2018): [3.6] = 16.850 (0.059), [4.5] = 14.069 (0.017)

Notes

• As noted by Cushing et al. (2015), Schneider et al. (2015) dropped the pec? in the spectral type by mistake.
