Research Type Experimental We analyze two simulated data sets that illustrate the identifiability statements from Sections 2.1 and 2.2. ... In Fig. 6, we present corrected light curves for three typical stars of different magnitudes, using both CPM and PDC. ... Fig. 7 presents our CDPP comparison of CPM and PDC, showing that our method outperforms PDC.

Pseudocode No The paper does not contain structured pseudocode or algorithm blocks.
Open Source Code Yes Our code is available at https://github.com/jvc2688/Kepler Pixel Model.
Open Datasets Yes We obtained the data from the Mikulski Archive for Space Telescopes (MAST) (see http://archive.stsci. edu/index.html).
Dataset Splits Yes We train the model separately for each month, which contains about 1300 data points. Standard L2 regularization is employed to avoid overfitting, and parameters (regularization strength and number of input pixels) were optimized using cross-validation.
Hardware Specification No The paper does not provide specific hardware details (e.g., exact GPU/CPU models, processor types) used for running its experiments.
Software Dependencies No The paper mentions using 'the function gam (penalized regression splines) from the R-package mgcv' but does not provide specific version numbers for R or the mgcv package.
Experiment Setup Yes Specifically, we use 4000 predictor pixels from about 150 stars... Standard L2 regularization is employed to avoid overfitting, and parameters (regularization strength and number of input pixels) were optimized using cross-validation. We train the model separately for each month, which contains about 1300 data points... we report results where the AR component uses as inputs the three closest future and the three closest past time points, subject to the constraint that a window of 9 hours around the considered time point is excluded.
