     - string
     - Number of spatially-coincident detections falling within 1.5 arcsec going back to beginning of survey; only detections that fell on the same field and readout-channel ID where the input candidate was observed are counted. All raw detections down to a photometric S/N of ~ 3 are included.
   * - ncovhist
     - integer
     - Number of times input candidate position fell on any field and readout-channel going back to beginning of survey
   * - mjdstarthist
     - number
     - Earliest Modified Julian date of epoch corresponding to ndethist [days]
   * - mjdendhist
     - number
     - Latest Modified Julian date of epoch corresponding to ndethist [days]
   * - corrected
     - boolean
     - Whether the corrected light curve was computed and can be used
   * - stellar
     - boolean
     - Whether the object is a likely stellar-like source

     - Total number of detections for the object
   * - g_r_max
     - number
     - Difference between the minimum g and r band difference magnitudes ( min(g) - min(r) )
   * - g_r_max_corr
     - number
     - Difference between the minimum g and r band corrected magnitudes  ( min(corrected(g)) - min(corrected(r)) )

     - number
     - Difference between the mean g and r band difference magnitudes ( mean(g) - mean(r) )
   * - g_r_mean_corr
     - number
     - Difference between the mean g and r band corrected magnitudes ( mean(corrected(g)) - mean(corrected(r)) )
   * - firstmjd
     - number
     - First detection's modified julian date
   * - lastmjd
     - number
     - Last detection's modified julian date
