[ascl:1306.006] BEHR: Bayesian Estimation of Hardness Ratios
Park, T.; Kashyap, V. L.; Siemiginowska, A.; van Dyk, D.; Zezas, A.; Heinke, C.; Wargelin, B. J.
BEHR is a standalone command-line C program designed to quickly estimate the hardness ratios and their uncertainties for astrophysical sources. It is especially useful in the Poisson regime of low counts, and computes the proper uncertainty regardless of whether the source is detected in both passbands or not.
[ascl:2505.017] TD-CARMA: Estimates of gravitational lens time delays with flexible CARMA processes
Meyer, Antoine D.; van Dyk, David A.; Tak, Hyungsuk; Siemiginowska, Aneta
TD-CARMA estimates cosmological time delays to model observed and irregularly sampled light curves as realizations of a continuous auto-regressive moving average (CARMA) process using MultiNest (ascl:1109.006) for Bayesian inference. TD-CARMA accounts for heteroskedastic measurement errors and microlensing, an additional source of independent extrinsic long-term variability in the source brightness.
