and H20 (MgII).

  Fixed a bug in the PS1 lightcurve data that led to incorrect
calculations of PS1_NMAG_OK and PS1_RMS_MAG. The main table
and the ancillary PS1_MD07_LC_sdssrm.fits table are both updated.

  Added F_H_5100, SIGMA, SIGMA_ERR and SIGMA_ERR_WARNING from 
Tab 1 in Shen++(2015b)

  Added Mi(z=2) and Mi(z=0) columns

  * forced zsys of RM113 and RM785 to be zpip, due to incorrect 
zsys estimation based on line fits. Also checked the remaining 
11 objects where zsys and zpip differ by >2000 km/s. Only for 
RM039 and RM284 zsys may be worse than zpip (but still somewhat 
ambiguous), and in all other 9 cases, zsys is better (although 
some further refinement is possible). 
  * populated columns LOGFNU2500A_ERGS_OBS and R_6CM_2500A for 
objects with spectral coverage at rest-frame 2500A.
