SQL Schema: Tables
Important announcements
The database for AKARI CAS was restructured into multiple databases.
The 'cas' database is available as a new database instead of 'DR1'.
Due to the reconfiguration of the database, the name of some tables and views had changed.
If you keep the previously created SQL and want to use again, please do substitution of the name.
And also, the usage of some functions had changed.
The correspondence between the new name and the old name is written in
Tables and
Views.
In Functions, please specify the catalogue names ('akari_fis_bsc_1' or 'akari_irc_psc_1')
instead of the instrument ('Fis' or 'Irc').
We appreciate in your inconvenience.

flags_65 | INT2 | S | A 16-bit flag per band indicating various data condition.
In version 1 catalogue three bits are used.
The first bit (bit0) is used to indicate
the CDS sampling mode. The second bit (bit1) warns
the flux of the band is less than a half of the detection limit,
and is not reliable. The fourth bit (bit3) tells that
the source is possibly false detection due to `side-lobe' effects
(see, Section 7.7
of the
Release Note).
The third bit (bit2) was
previously indicated an anomaly which does not exist in the
current version, and thus is kept unused.
Sources with bit1 or bit3 = 1 have fQual_65 = 2 or less.
Other bits are reserved for the future implementation.
