+%proposal for taking into account VEP for analysis products and response function 
+%\newpage
+\subsubsection{Summary Table}
+
+The proposed vocabulary entries are listed in Table~\ref{tab:dp_vocabulary} with their labels and parents identified. Two vocabularies are proposed for response functions and analysis products following the semantics procedure for VEPs (see \url{https://github.com/ivoa-std/VEPs}).

+\multicolumn{4}{|r|}{\bf Added to \emph{product-type} Vocabulary  \url{https://www.ivoa.net/rdf/product-type/}} \\ \hline
+{\bf hea-event-bundle} & Event Bundle & A compounded dataset containing containing an {\bf hea-event-list} and multiple files or other substructures that are products necessary to analyze the {\bf hea-event-list} & none \cr
+{\bf hea-event-list} & Event list & A dataset that records a collection of observed particle-detection events, such as incoming high-energy particles, where an event is typically characterized by a spatial position, a time, and a spectral value ({\em e.g.\/}, an energy, a channel, a pulse height) & none \cr
+ \hline
+\multicolumn{4}{|r|}{\bf Added to \emph{response-type} vocabulary  \url{https://www.ivoa.net/rdf/response-type/} } \\ \hline
+{\bf response-function} & Response Function & A dataset that maps a physical quantity to an observable quantitiy. This term is mainly intended for retrieval. To annotate datasets, use a narrower term Narrower terms are preferred to indicate more precisely the type of {\bf response-function} & \cr
+{\bf rmf} &\raggedright Redistribution Matrix File & A dataset that records the probability density function mapping from energy space into detector pulse height (or position) space & \#response-function \cr
+{\bf aeff} & Effective Area & A dataset that records the ``effective area'' of a telescope and/or instrument.  The effective area is the geometric area of the telescope and/or instrument reduced by efficiency factors such as reflectivity and vignetting, among other effects & \#response-function \cr
+{\bf arf} &\raggedright Ancillary Response File & A dataset that records the combined telescope/instrument effective area and detector quantum efficiency as a function of energy & \#response-function \cr
+{\bf bkgrate} & Background Rate & A dataset that models the rate of residual events that are not from the expected source type ({\em e.g.\/}, for gamma-ray instrument {\bf bkgrate} measures residual non-gamma-ray events coming from charged cosmic rays) & \#response-function \cr
+{\bf edisp} & Energy Dispersion & A dataset that records the probability density of detecting an event with an energy estimator (proxy) given the true energy of the event & \#response-function \cr
+{\bf psf} &\raggedright Point Spread Function & A dataset that records the probability density function of spatial/angular spreading of incident particles from a point source caused by the instrument (detector and/or mirror and/or analysis) & \#response-function \cr  \hline
+\multicolumn{4}{|r|}{\bf Added to \emph{analysis-product} vocabulary \url{https://github.com/ivoa-std/VEPs}} \\ \hline
+{\bf draws} & Draws & A dataset that records statistical draws computed from a probability distribution, for example Markov chain Monte Carlo (MCMC) draws used when computing the Bayesian marginal probability density function for a random variable & none \cr
+{\bf pdf} &\raggedright Probability Density Function & A dataset that records the probability density function of a quantity, for example the Bayesian marginal probability density function for a random variable & none \cr
+{\bf region} & Region & A dataset that encodes (one or more) regions of parameter space, for example a spatial region or a region of phase space covered by a dataset. The set of dimensions represented by the region can be arbitrary & none  \cr
