| 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. | ||||||
