Abstract

This repository contains NEOWISE infrared lightcurves and SPHEREx spectrophotometry for eight Galactic outbursts presented in the paper SPHEREx as a frontier for infrared transients: Classification of new Galactic FU Ori outbursts and classical novae. It also contains the ATLAS optical lightcurve for the new classical nova WTP24abacpo. Content description :- The filenames describe the contents and the target names (e.g., spherex_spec_WTP24abacpo.csv). All files are standard csv files, and can be read using standard python methods such as pandas.read_csv. NEOWISE lightcurve files contain five columns : MJD (Modified Julian Date) forced psf flux measurement in micro-Janskys, uncertainty on the psf flux in micro-Janskys, the band (W1 or W2) a boolean flag indicating whether the measurement corresponds to a detection or an upper limit. For upper limits, the 5-sigma limiting flux can be calculated as 5*psffluxunc_ujy. The ATLAS lightcurve file contains four columns : mjd (Modified Julian Date) filter : atlaso or atlasc Flux : Forced PSF flux in micro-Janskys. Nan values indicate on-detections. fluxunc_ujy : Forced PSF flux uncertainty in micro-Janskys SPHEREx spectra files contain several columns generated by the SPHEREx spectrophotometry tool. We refer users to the SPHEREx documentation at IRSA for a description of these columns. IRTF spectra files contain two columns : lam : wavelength in microns flambda : flux density in erg/s/cm^2/Angstrom.
