Target Notes

Open a color composite thumbnail image of M31-004130.37

Classification: Of/late-WN

Sometimes unresolved from LGGS star J004130.23+410501.6 and two others that combine to be comparable brightness to target 2 arcseconds WNW. Xed out when only one star is fit. Marked B when PSF fit is shows significant negative sharpness value. Suspect that one or more of the blended stars is a variable and that can sometimes influence the PSF fit.

Variability

Plot/Graph Photometry Table Target Notes

From the data available in this survey, it is not possible to tell with certainty if this star is variable.

Correlation factors between bands

If the brightness variation is true variability then there should be a correlation between brightness changes recorded in different filter bands. The following table are the R-squared linear correlation factors calculated for the pairs of bands. The number in parentheses next to the R-squared value is the number of elements used to calculate the correlation factor. The number in square brackets next to the band is the range of magnitudes measured.

V [1.05 mag]B [0.69 mag]R [0.49 mag]
B [0.69 mag]0.03 (38)
R [0.49 mag]0.11 (37)0.24 (25)
I [1.43 mag]0.08 (23)0.05 (14)0.22 (15)

I & R Statistics

Welch & Stetson (1993, AJ, 105, 1813) present a method for varible star detection in CCD images from automated surveys. Data from two bands are compared and two statistics are calculated: R and I.

The I-statistic has an expectation value of zero for stars that are NOT variable. A larger non-zero I-value indicates a higher likelihood that the star is variable. The R statistic indicates how the color of the star changes as the variable grows brighter with R = 1.0 being no change in color.

R and I values have only been calculated if there are more than four (4) matched measurements of brightness in each band.
