Fluxes

class prose.Fluxes

Photometric fluxes, from single to multiple stars and apertures.

Also hold contemporary time-series, errors and apertures properties.

Methods

__init__(fluxes[, time, errors, data, ...])
autodiff()	Automatic differential photometry with Broeg et al. 2005.
best_aperture_index([method, sigma])	Find index of best aperture
bin(size[, estimate_error])	Returns a Fluxes instance with binned time series
copy()
diff([comps])	Differential photometry
errorbar([color, fmt])	Error bar plot of the light curve
estimate_best_aperture([target, method, sigma])	Inplace setting of best aperture.
estimate_error()
load()
mask(array)	Mask time-dependant fluxes attributes (time, fluxes, errors, data)
mask_stars(mask[, keep_indexing])	Mask stars fluxes.
plot([marker, color, ls, ax])	Plot light curve
save(path)	Save fluxes to file
sigma_clip_flux([iterations, sigma])	Return a Fluxes instance masked using iteratively sigma clipping.
sigma_clipping_data([iterations])	Return a Fluxes instance masked using iteratively sigma clipped data.
vander(**kwargs)
