The data for ZTF IC 10 variable catalog

Catalogs are in either csv file, or Astropy QTable ecsv format. ZTF r band catalog: df_zr.csv / t_zr_20250225.ecsv ZTF g band catalog: df_zg.csv/ t_zg_20250225.ecsv color catalog: df_color.csv / t_color_0912.ecsv Scheme for df_[band].csv, also see Table 4 in the Jin & Gelfand 2025: Label Units Explanations SourceID --- Source ID for this lightcurve/OID. OIDs with less than 1'' have the same SourceID filter --- ZTF filter, either zr for r band or zg for g band OID --- ZTF Object ID. Each OID has a lightcurve and makes up a row in this paper's catalog RA deg Right ascension, from ZTF (J2000) DEC deg Declination, from ZTF (J2000) numobs --- Number of observations by ZTF, or number of points of this lightcurve sf --- The S_k_({chi}^2^), survival function of the constant magnitude model, to classify variable vs. non-variable FAP --- False alarm probability from Lomb-Scargle, to classify periodic variable vs. non-periodic variable period d Period at Lomb-Scargle periodogram peak power. Period of the source if the source is periodic period_w d Period at window function peak power power --- Lomb-Scargle periodogram peak power power_w --- Window function power mean mag Mean magnitude std mag Standard deviation of magnitudes min mag Minimum magnitude max mag Maximum magnitude upsilon_class --- Classification label from UPSILoN upsilon_prob --- Classification probability from UPSILoN upsilon_flag --- Suspicious classification flag by UPSILoN upsilon_period d Period found by UPSILoN identifier --- SIMBAD database identifier of the nearest (if there is any) match within 2'' dist arcsec Angular distance between ZTF location and SIMBAD location of the nearest match type --- SIMBAD object type of the nearest match Gaia_count --- Number of Gaia objects within 2'' radius multiflag --- If there is possible contamination from multiple unresolved sources, see Section 4.4 GaiaDist arcsec Angular distance between ZTF location and Gaia location of the brightest match fluxratio --- Gaia G band flux of brightest Gaia match over that of second brightest Gaia match Gmag mag Gaia G band magnitude Plx mas Parallax of the brightest Gaia match e_Plx mas Error in parallax of the brightest Gaia match Plxflag --- If the source is outside IC 10, 1=outside, 0=inside. RUWE --- Renormalised Unit Weight Error of the brightest Gaia match XMM --- Number of XMM objects XMM_dist arcsec Angular distance between between ZTF location and XMM location Chandra --- Number of Chandra objects Chandra_dist arcsec Angular distance between between ZTF location and Chandra location inside_flag --- If the source is within the 25{sigma} overdensed region. See Section 4.5 ic10_flag --- If the source is likely to be inside IC 10, with Plxflag=0 and inside-flag=1. See Section 4.5 lc_var --- Classification of this lightcurve/OID. P = periodic variable, V = non-periodic variable, N = non-variable. var --- Classification of this source, P/V/N var_flag --- suspect flag, see Section 3.3 Scheme for df_color.csv, note that only sources have both zr and zg observations are included: Label Units Explanations SourceID --- Source ID for this lightcurve/OID. OIDs with less than 1'' have the same SourceID. mean_color mag Mean g-r color std_color mag Standard deviation of g-r color max_color mag Maximum g-r color min_color mag Minimum g-r color mean_mag_r mag Mean r band magnitude std_mag_r mag Standard deviation of r band magnitude max_mag_r mag Maximum r band magnitude min_mag_r mag Minimum r band magnitude mean_mag_g mag Mean g band magnitude std_mag_g mag Standard deviation of g band magnitude max_mag_g mag Maximum g band magnitude min_mag_g mag Minimum g band magnitude var --- Classification of this source. P = periodic variable, V = non-periodic variable, N = non-variable. Plxflag --- If the source is outside IC 10, 1=outside, 0=inside. ic10_flag --- If the source is likely to be inside IC 10, with Plxflag=0 and inside-flag=1. See Section 4.5 type --- SIMBAD object type of the nearest match XMM --- Number of XMM objects Chandra --- Number of Chandra objects intrinsic_mag_r mag Intrinsic r band apparent magnitude for IC 10 sources, corrected for extinction and reddening of IC 10. See Section 5.1. intrinsic_color mag g-r color calculated with intrinsic apparent magnitudes absolute_mag_r mag Absolute r band magnitude, converted from intrinsic apparent magnitudes according to its parallax (foreground sources) or IC 10 distance (IC 10 sources).
