Recommended parameters for the Gaia Spectro-Photometric Standard stars (gaiadr3.gold_sample_spss)
The table has 111 rows, 35 columns.
Description
Recommended parameters for the Gaia Spectro-Photometric Standard stars (Pancino et al. 2021), selected as described in DR3-DPACP-123, from the available parameters produced by CU8 DR3-DPACP-157 and CU6 DR3-DPACP-159.
Known issues
Two incorrect source_ids in gaiadr3.gold_sample_spss
An error has occured in the gaiadr3.gold_sample_spss table. Namely two source_ids were incorrectly labelled. This concerns only the source_ids and no other data field. The error has been traced back to an early cross-match on the SPSS tables and we confirm that no other source has been affected by this.
Therefore in the current gaiadr3.gold_sample_spss, the following should be replaced:
- SPSS_ID = 348, HD271783 has a true Gaia DR3 source_id = 5284204302730217984 and not 4887062351834002642
- SPSS_ID = 115, G114-25 has a true Gaia DR3 source_id = 5757389920689415040 and not 4887524447164040921
