Learn the file name template for science products |
On this page... |
Names of science files must follow the naming scheme described here. This convention permits easy integration with MAST in a way that allows for automated searches. Components of file names in black bold text, including underscores and periods, are literal text; items in green italic text are symbolic, and are explained below. The name template is:
hlsp_proj-id_observatory_instrument_target_opt-elem_version_product-type.extension
Where the components are:
Component | Description |
---|---|
hlsp | A literal string that identifies the file as a community-contributed data product |
| An agreed upon identifier for the HLSP collection (e.g. a project acronym). This name is also used in MAST as directory name and as a database keyword. |
| Primary observatory used to acquire the data. If multiple observatories were used, acronyms may be separated by hyphens (e.g., hst-fuse ). |
instrument | Instrument acronym (and if applicable, channel) used to obtain the data (e.g. |
target | Field name or target as designated by the team. Parts, counter numbers, and epochs are allowed in this field and should be separated by hyphens. Counters can be used when the same field is observed multiple times with the same observing parameters.
Please describe your usage of field-name parts and counters within the collection README file. |
opt-elem | Names of optical element(s) (i.e., filter or dispersing element) used to obtain the data.
|
version | Version designation used by the team for the HLSP delivery, such as |
product-type | Type of data as designated by the team (models/simulations can be indicated here). Please use a widely recognized type when possible; examples include: |
extension | Standard extension name for the file format, e.g. |

A 1-D SED of the target AV-95 from the ULLYSES survey, obtained with HST/STIS and FUSE (note that multiple gratings were used, so the spectral element is just referred to as uv
