in the Channel 1 ($3.6~\mu$m) and Channel 2 ($4.5~\mu$m) bands as part of the Cycle 14 Program: “Weather and Rotation of Young Brown Dwarfs” (PID: 14019). We observed each target for twice their rotation period in both bands, resulting in a total observation duration of $12.8$ hr, $39.2$ hr and $11.2$ hr for , and respectively. The observations were designed following the recommendations for obtaining high precision photometry from the Spitzer Science Center. Science observations were preceded by a 30-minute dithered sequence to remove the initial slew settling that occurs when acquiring a new target, and followed by a 10-minute dithered sequence. The target was placed on the well-characterized “sweet spot” of the detector for science exposures to minimize correlated noise.

![Raw *Spitzer*/IRAC photometry obtained from aperture photometry is highly correlated with $x$ and $y$ sub-pixel positions. We correct for this by fitting a cubic function. Top panels show the correlation between the raw flux and pixel position. Bottom panels shows the corrected flux plotted against pixel position. Spearman’s $\rho$ coefficient is a measure of the significance of correlation between two values – in all cases Spearman’s $\rho$ coefficient decreases after pixel phase correction.
