Monitored source V3890 Sgr

Monitored source V3890 Sgr - recurrent nova

Position: 18:30:43.29 -24:01:08.9 · cameras: TTUQ1b1x1 TTUQ2b1x1 · 0 detections, 210 upper limits · 65 excluded from the lightcurve

Manual detection threshold: measurements fainter than mag 13.00 are published as upper limits at the measured magnitude, because the photometric aperture is contaminated by light from an unrelated nearby source. Below that threshold a measurement only bounds the target brightness from above; only when the target outshines the contaminant does a measurement count as a detection (status below_threshold in the table below marks the demoted measurements).

Why these photometric measurements are not very precise

Photometric measurements obtained with a wide-field camera are not very precise, for a number of reasons:

Bad plate solution: errors in the astrometric calibration result in misplacement of the photometric aperture. This may create outlier measurements.
Undersampled PSF: star images occupy only a few pixels, so any uncorrected pixel-to-pixel and intra-pixel sensitivity variations affect the measurements more than they would for well-sampled telescopic images in which each star is spread across many pixels.
Low observing altitude: the fields are often imaged only 15-20 degrees above the horizon. This is a deliberate trade-off for an all-sky transient search, as the sky area at low elevation is far larger than the area near the zenith, but it is bad for photometric accuracy. An airmass-dependent magnitude zero-point correction is applied, but it is not perfect.
Color-dependent (second-order) extinction: a star's brightness measured relative to the comparison stars in the field is elevation-dependent if the star's color differs from the average color of the comparison stars.
Blending with nearby stars in crowded fields affects the measurements differently depending on the aperture size, which is adjusted for each image individually based on the seeing and focus quality.
Position-dependent PSF: the same star may fall closer to the image center in one field and farther from it in another, so a different fraction of its PSF is covered by the aperture even when the same aperture is used to measure both images. Field-to-field and camera-to-camera calibration is therefore an issue, and its magnitude differs from source to source.
Chromatic aberration: many wide-field lenses suffer from it, leaving extremely red stars out of focus while the focus is optimal for average-colored stars.
Clouds, if present, dramatically degrade the quality of the photometry across the entire image.

In practice, expect a photometric uncertainty of ~0.1 mag, or somewhat better in favorable conditions.

The intended use of these data is a quick check of the current state of a source (flaring or quiescent) - not precise photometry.

The photometric measurements are performed without a filter; the zero-point of the instrumental magnitude scale is set by the V magnitudes of the field stars. You are welcome to use these data in any way you see fit, providing a link to this page as the origin of the data.

Measurements excluded from the lightcurve

These measurements are excluded from the lightcurve, the plot and the AAVSO file. Reason visit_inconsistent: frames of the same field taken minutes apart disagree by more than the expected measurement scatter - a real star cannot change that fast, so at least one frame of the visit is corrupted (typically by patchy clouds) and there is no way to tell which one. Reason cloudy_frame: the frame failed the cloud check - its field stars disagree with the reference frame in a way uniform transparency loss cannot explain. The remaining reasons mean the measurement could not be made on that image at all, so no magnitude is shown: bad_ccd_region - the position falls on a masked part of the detector (bad_region.lst of that camera); saturated - the star is there but too bright to measure; blank_pixels_in_aperture, magnitude_calibration_failed and measurement_failed - the aperture contained blank pixels, the frame could not be calibrated, or the measuring tool failed. These images WERE taken and WERE measured: they are listed here so that a rejected measurement is never mistaken for a gap in the coverage. The excluded rows are kept in excluded_measurements.dat.
