 gwcelery.tasks.em_bright module
 -------------------------------
 
+This module computes the probabilities that there is a neutron star in
+the binary, and that the coalescence event resulted in creation of tidally 
+disrupted matter.
+
+The result is returned in the form of a JSON file:
+
+'{"HasNS": 1.0, "HasRemnant": 1.0}'
+
+* ``HasNS``: The probability that at least one of the component masses
+             in  the binary is a neutron star. The definition of a
+             neutron star in this context simply means an object with 
+             mass less than 3.0 solar mass.
+
+* ``HasRemnant``: The probability that the binary system can produce
+                  tidally disrupted matter during coalescence. This is
+                  computed using the fitting formula in :arxiv:`1807.00011`
+                  We are currently using an extremely stiff equation of
+                  state (2H) to compute the compactness of the neutron
+                  star. This results in a higher chance of labelling
+                  a systems with non-zero ``HasRemnant`` value.
