CSN meaning in Unclassified in Miscellaneous
CSN mostly used in an acronym Unclassified in Category Miscellaneous that means Catalogue Sequence Number
Shorthand: CSN,
Full Form: Catalogue Sequence Number
For more information of "Catalogue Sequence Number", see the section below.
Purpose of CSN
- Provide a unique and consistent way to identify items in a catalogue.
- Enable quick and accurate retrieval of item information.
- Facilitate efficient organization and tracking of items.
Format and Structure
CSNs typically follow a specific format and structure, which may vary depending on the context and the system they are used in. Common formats include:
- Numeric: A sequence of digits, e.g., 12345.
- Alphanumeric: A combination of letters and numbers, e.g., ABC123.
- Hierarchical: A structured sequence of numbers or letters that indicate the item's position within a hierarchy, e.g., 1.2.3.
Uses of CSN
CSNs are widely used in various industries and applications, including:
- Libraries: To identify and manage books, journals, and other library materials.
- Museums: To catalogue and track artifacts, specimens, and artworks.
- E-commerce: To assign unique identifiers to products and orders in online marketplaces.
- Databases: To organize and retrieve data efficiently, particularly in large and complex datasets.
Conclusion:
The Catalogue Sequence Number (CSN) is a valuable tool for managing and accessing information in catalogues and databases. It provides a unique and consistent way to identify and retrieve items, making it easier to organize, track, and access information efficiently.
Essential Questions and Answers on Catalogue Sequence Number in "MISCELLANEOUS»UNFILED"
What is a Catalogue Sequence Number (CSN)?
A Catalogue Sequence Number (CSN) is a unique identifier assigned to each astronomical object catalogued by the Smithsonian Astrophysical Observatory (SAO). It serves as a reference number for locating and identifying celestial objects in the SAO Star Catalogues.
What is the purpose of a CSN?
The primary purpose of a CSN is to provide an unambiguous way to identify astronomical objects, particularly stars, in scientific research and astronomical databases. It allows astronomers to refer to specific objects consistently and retrieve information about them from catalogues and other sources.
How is a CSN assigned to an astronomical object?
CSNs are assigned sequentially as astronomical objects are observed and catalogued. The SAO Star Catalogues, which contain billions of stars, assign CSNs based on the object's position in the sky and its brightness.
Where can I find the CSN of an astronomical object?
The CSN of an astronomical object can be obtained from various astronomical databases, such as the SIMBAD Astronomical Database and the Vizier catalogue service. It is often included in scientific publications and research papers related to the object.
What are the limitations of CSNs?
While CSNs are useful identifiers, they can become outdated as new catalogues emerge or observations refine our understanding of astronomical objects. Additionally, they are not always unique across different catalogues, and it is essential to consider the context and source of a CSN to ensure its relevance.
