An {\bf event-bundle} might for example consist of an {\bf event-list} and the associated {\bf response-function}s used to calibrate the dataset, and may also contain provenance information, data quality time-series, and preview images or plots.



\subsubsection{Advanced Data Products}

In addition to data product types that focus on event data, we note that existing ObsCore definitions do not adequately span the breadth of advanced data products (typically with {\em calib\_level\/}${}\ge 3$) that may be generated from astronomical observations. The computational complexity of analyzing \gls{HEA} data robustly in the extreme Poisson regime ({\em e.g.\/}, Bayesian X-ray aperture photometry applied simultaneously to multiple overlapping detections and observations) means that data providers may choose to provide such analysis products directly to the end user.

New Term: response-function
Action: Addition
Label: response-function
Description:
A data product type describing instrumental response functions for calibration and analysis.

Relationships: response-function is a top level term.
Usually related to an event-list data product in high energy astrophysics.

Used-in: Data sets made accessible via the Chandra CS2 catalog

Rationale:
The distribution of event-list data in multi-messenger astronomy.
For example, Chandra primary products distributed via the Chandra
Data Archive include around half a dozen different types of products neces-
sary to analyse Chandra data (for example, L2 event-list, Aspect solution,
bad pixel map, spacecraft ephemeris, V&V Report).
For VHE gamma rays and neutrinos, the DL3 event-lists should manda-
torily be associated to their associated IRFs files. The links between the
event-list and these IRFs should be well defined in the event-bundle.
