Photometric Standard stars

A catalogue with selected photometric standard star fields is available from the TCS (stphot.cat). These fields have three or more "well" observed stars from Landolt, A. 2009 AJ 137 4186. The full catalogue (exluding the TPhe-field) ia also available (landolt_aj_137.cat) and the old Landolt, A. 1992 AJ 104 340 version as landolt_aj_104.cat)

The easiest way to access these stars are using goto-object TCS-command e.g.
tcs.goto-object ST_GD71 from the sequencer terminal or
goto-object ST_GD71 from the TCS.


The suggested integration times are not yet included for every field.

Some other standard star catalogues:

SDSS standard Star Catalog for Stripe 82
This catalog lists positions and ugriz photometry for 1,006,849 candidate standard stars from SDSS stripe 82:
|Dec|<1.266 deg and RA in the range 20h 34m to 4h 00m; about 300 sq.deg.

Stetson Photometric Standard Fields
229 fields, with BVRI photometry, some southern fields; see also Stetson P.B. PASP, 112, 925, 2000
A catalogue of "Stetson" standard stars with declination > -40deg is available from the TCS (stetson.cat).
Stetson fields in the TCS-catalogue have a prefix "S_" e.g. "S_Ru149".

Selected fields BVRI photometry: NGC2419 (approximate centre RA=07h38m10s dec=+39:52:56), Pal4 (RA=11h29m15s dec=+28:58:26)
Pal14 (RA=16h11m00s dec=+14:57:45) Saha, A. et al, PASP, 117, 37 (2005). About NGC2419 see also Stetson, P.B. PASP 117, 563 (2005)
