[ascl:2103.010] TransitFit: Exoplanet transit fitting package for multi-telescope datasets
Hayes, J. J. C.; Kerins, E.; Morgan, J. S.; Humpage, A.; Awiphan, S.; Charles-Mindoza, S.; McDonald, I.; Inyanya, T.; Padjaroen, T.; Munsaket, P.; Chuanraksasat, P.; Komonjinda, S.; Kittara, P.; Dhillon, V. S.; Marsh, T. R.; Reichart, D. E.; Poshyachinda, S.
TransitFit fits exoplanetary transit light-curves for transmission spectroscopy studies. The code uses nested sampling for efficient and robust multi-epoch, multi-wavelength fitting of transit data obtained from one or more telescopes. TransitFit allows per-telescope detrending to be performed simultaneously with parameter fitting, including the use of user-supplied detrending alogorithms. Host limb darkening can be fitted either independently ("uncoupled") for each filter or combined ("coupled") using prior conditioning from the PHOENIX stellar atmosphere models. For this, TransitFit uses the Limb Darkening Toolkit (ascl:1510.003) together with filter profiles, including user-supplied filter profiles.
[ascl:1406.002] PAMELA: Optimal extraction code for long-slit CCD spectroscopy
Marsh, Thomas R.
PAMELA is an implementation of the optimal extraction algorithm for long-slit CCD spectroscopy and is well suited for time-series spectroscopy. It properly implements the optimal extraction algorithm for curved spectra, including on-the-fly cosmic ray rejection as well as proper calculation and propagation of the errors. The software is distributed as part of the Starlink software collection (ascl:1110.012).
