Proposal for Registering a New Acronym |
1. | For a designation based on a sequential numbering: | ||
sample 102 | give in one of the examples the highest number | ||
2. | For designations based on coordinates: | ||
choose two examples (if possible, both a positive and negative Dec or latitude) and give a brief explanation which includes the actual coordinates of the source to illustrate proper truncation | |||
a. For a designation based on J2000 position: | |||
sample J195740.55+333827.9 |
for a source with actual J2000 position: RA=19h57m40.558s, Dec=+33°38'27.96'' (truncation rule) | ||
b. For a designation based on B1950 position: | |||
sample B19572+3348 |
for a source with actual B1950 position: RA=19h57m17.5s, Dec=+33°48'58" (truncation rule) | ||
c. For a designation based on galactic coordinates: | |||
sample G330.7-00.3 |
for a source with actual galactic coordinates: longitude= 330.72°, latitude=–0.36° |
Registry of an acronym is especially advantageous for large, on-going surveys where images and source lists may be produced in stages and/or may be published in electronic form before the final printed catalogue. Registering the acronym ensures the availability of a suitable, unique acronym for the survey and that the proposed designation conforms to the IAU recommendations. This would go a long way toward catching and eliminating some potentially confusing and inadvertently non-conforming designations BEFORE they appear in print or in the data archives. Your cooperation is appreciated.
