Object properties

This page provides details for the Target and Alert team about the basic light curve and host parameters of ePESSTO science group targets. If you are the science P.I. of an ePESSTO science project, please add details in the table below for your transient classes.  If a category doesn't apply to your science case, just leave it blank.

Science group titleP.I science group and emailObject class
Rise time to maximum light   
Typical mag. increase to max.  
Absolute peak magnitude
Host galaxy type and preferred location
Redshift range of interest for science case
Phase range of interest for latest spectroscopic classification (i.e. must be at least X days before peak, at max., etc.)
Source of targets (particular survey or all?)
Additional relevant information (e.g. multiple peaks, pre-explosion outbursts, etc.)

 Any galaxy. Even more interesting if in low-L hosts.    
 z<0.1 Up to several weeks past estimated explosion epoch. However, the brighter the SN, the later it is still interesting to get the classification.
