Surveys included:
| Survey | Telescope / Instrument | Filters (detection band in bold) | Location |
|---|---|---|---|
| Legacy Survey | BASS | grz | dmu0_LegacySurvey |
| UHS | UKIRT | J | dmu0_UHS |
NB: On XMM-13hr, there are no bands with multiple
observations. We then cannot flag outliers or look for difference in
aperture correction between point-source and extended objects for
different surveys.
Also, there are no sources, with "weird" magnitude or magnitude error, to flag in this field.
xxxxxxxxxxAt faint magnitudes (mag > 24), __Legacy Survey__ have very large errors on the __aperture and total__ magnitude (at mag > 27). These objects may be unreliable for science puposes.<br><img src="help_plots/XMM-13hr_magVSmagerr_BASS_g_mag_total.png" />At faint magnitudes (mag > 24), Legacy Survey have very large errors on the aperture and total magnitude (at mag > 27).
