SVISS Supernova candidates, second screening
The total number of candidates in the different quadrants are:
B1: 9
A2: 11
A3: 5
B4: 6
New stuff in this version:
The image cutouts now also contain 3 panels
(in the upper right corner) with the image region one year before the
search epochs, one year after and a subtracted frame using these.
The light curve fits have been done using host photometric redshifts.
An additional light curve template have been used, Iafaint, a
low stretch Ia template.
For each candidate the following information is available:
- Identification number and quadrant (e.g. a2-12)
- Best fitting template
- Best fitting parameters with the above template,
MB(peak) is the fitted absolute magnitude at peak,
zfit is the fitted redshift of the SNe, te
is the teomporal offset in days between the explosion date and the
first search epoch and extmod is the extinction model (1-7 Cardelli
with RV=3.1, 8-14 Cardelli with RV=2.1 and
15-21 Calzetti and E(B-V) from 0 to 0.6 for each).
- Fitting quality (P/L/chisq) for the above template
- Host galaxy magnitude, mI(host)
- Host photometric redshift, zp (1 sigma uncertainty)
- A panel with the observed light curve plot (R, I, R-I) and the
best fit light curve for each template.
- A panel with the image stamps, containing the reference image,
the seven detection images and the seven subtracted images.
Go through the candidates looking at both image cutouts and the light curve fits,
give each of them a rating according to:
- A, primary SN candidate
- B, secondary SN candidate, typing questionable/difficult
- X, not a supernova, likely AGN
- 0, not a supernova, likely nothing
No need for detailed comments on every candidate, we'll discuss the problematic
cases once I've gotten comments.
