When using ASAS-SN light curves in publications cite: Shappee et al. (2014) and Kochanek et al. (2017)

Important Update (September 2018)

We are now serving both V-band (Cameras ba-bh) and g-band (Cameras bi-bt) photometry, see "Examples" link below for details.


V-band and g-band magnitudes obtained via this page are calculated in real-time using aperture photometry, with zero-points calibrated using the APASS catalog. ASAS-SN images have 8" pixels (~15" FWHM PSF,) so blending/crowding might be significant in some cases. The "Examples" page linked below, and Kochanek et al. (2017) paper, illustrate some of the potential problems. Always proceed with caution before publishing. This page is meant to obtain a relatively small number of light curves - if you need light curves of many (>100) objects, please contact us.
