:TIC2

Revision as of 20:48, 12 October 2016

Set up some kind of "TIC2" catalogue, i.e. targets of interest in terms of full-frame quick look analysis. This catalogue needs to be

• literally full-sky;
• provided by a homogeneous instrumentation;
• have some sort of color information;
• down to 17-18m (i.e. S/N ~ 5-10 on 30min cadence);
• primary ID is needed to be assigned to a well-known catalogue;
• cross-match w/ as many (nearly or literally full-sky) catalogues as possible.

Candidates: USNO, UCAC, 2MASS... any more hints? Note: GAIA-DR1 is not full-sky, some stripes are missing (however, GAIA is perfect for FF astrometry)

UCAC4

Selecting sources with proper (non-null, well-defined)

• id
• ra,dec
• amag,err_amag
• err_ra, rr_dec
• pmra, pmdec, err_pmra, err_pmdec
• epoch_ra, epoch_dec
• id_2mass, Jmag, err_Jmag, Hmag, err_Hmag, Kmag, err_Kmag

Output:

• Total number of such sources: 79,607,988
• Homogeneity: seems to be homogeneous between 8.6 and 15.8 mags.
• Number of sources fainter than 15.8 quickly drops, the faintest source listed here is 16.4
• The catalogue seems to be complete for sources between 7.5 and 15.8 mags.
• Sources brighter than 7.5' are likely to be saturated.
