Data accompanying SPHEREx as a frontier for infrared transients: Classification of new Galactic FU Ori outbursts and classical novae

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.
