Query: Spitzer Secondary Eclipse Depths with Multiple Intrapixel Sensitivity
  Correction Methods: Observations of WASP-13b, WASP-15b, WASP-16b, WASP-62b,
  and HAT-P-22b   We measure the 4.5 $\mu$m thermal emission of five transiting hot Jupiters,
WASP-13b, WASP-15b, WASP-16b, WASP-62b and HAT-P-22b using channel 2 of the
Infrared Array Camera (IRAC) on the {\sl Spitzer Space Telescope}. Significant
intrapixel sensitivity variations in Spitzer IRAC data require careful
correction in order to achieve precision on the order of several hundred parts
per million (ppm) for the measurement of exoplanet secondary eclipses. We
determine eclipse depths by first correcting the raw data using three
independent data reduction methods. The Pixel Gain Map (PMAP), Nearest
Neighbors (NNBR), and Pixel Level Decorrelation (PLD) each correct for the
intrapixel sensitivity effect in Spitzer photometric time-series observations.
The results from each methodology are compared against each other to establish
if they reach a statistically equivalent result in every case and to evaluate
their ability to minimize uncertainty in the measurement. We find that all
three methods produce reliable results. For every planet examined here NNBR and
PLD produce results that are in statistical agreement. However, the PMAP method
appears to produce results in slight disagreement in cases where the stellar
centroid is not kept consistently on the most well characterized area of the
detector. We evaluate the ability of each method to reduce the scatter in the
residuals as well as in the correlated noise in the corrected data. The NNBR
and PLD methods consistently minimize both white and red noise levels and
should be considered reliable and consistent. The planets in this study span
equilibrium temperatures from 1100 to 2000~K and have brightness temperatures
that require either high albedo or efficient recirculation. However, it is
possible that other processes such as clouds or disequilibrium chemistry may
also be responsible for producing these brightness temperatures.
