New Reference catalog keys

New reference catalog keys were assigned for GAIA DR catalog and APASS catalog.

To be able to distinguish between different passbands that these catalogs contain the following new keys were assigned and can be used in the future.

GAIA DR1, DR2 and EDR3

New keys were assigned for GBP and GRP passbands. The description was rephrased to include all the catalog releases available.

Key Catalog name Catalog description
GG GAIA DR1, DR2, EDR3 G GAIA Data Release (GAIA DR1, DR2, DER3) G
BG GAIA DR1, DR2, EDR3 GBP GAIA Data Release (GAIA DR1, DR2, EDR3) GBP
RG GAIA DR1, DR2, EDR3 GRP GAIA Data Release (GAIA DR1, DR2, EDR3) GRP

 

The APASS catalog

The currently used key AQ was rephrased so that it does not specify the passband. New keys were assigned for individual passbands available in the APASS catalog.

Key Catalog name Catalog description
AQ APASS Unspecified passband The AAVSO Photometric All-Sky Survey (APASS) Unspecified passband
AB APASS Johnson B The AAVSO Photometric All-Sky Survey (APASS) Johnson B
AV APASS Johnson V The AAVSO Photometric All-Sky Survey (APASS) Johnson V
AR APASS Sloan r' The AAVSO Photometric All-Sky Survey (APASS) Sloan r'
AG APASS Sloan g' The AAVSO Photometric All-Sky Survey (APASS) Sloan g'
AI APASS Sloan i' The AAVSO Photometric All-Sky Survey (APASS) Sloan i'
AZ APASS Sloan z' The AAVSO Photometric All-Sky Survey (APASS) Sloan z'

 

For the reason of consistency in the keys, the AG key which was used for Astronomisches Gesellschaft Katalog was renamed (it was not widely used by observers). The new key for this catalog is GK.
