Research campaign of spring 2001

Table 7.2 fact the assessment of the countryside of spring 2001 carried out with the CFHT using the CFH12K. This countryside allowed, by observing two fields lasting 2 times three hours at 25 days of interval in filter I, to discover 4 supernovæ of the Ia type to redshifts ranging between 0.45 and 1.12. This countryside also allowed the discovery of 6 candidates who were too weak to allow the spectroscopic observation.

From the 4 supernovæ discovered with the CFHT, 3 was followed using the Hubble telescope. The supernova nearest as for it was followed with means on the ground.

Table 7.2: Summary table of the research campaign of spring 2001 with the CFHT. This countryside made it possible to discover 13 candidates of good quality with a signal on noise higher than 5 and one significant rate of increase in luminosity. 4 objects proved to be of the supernovæ of the type Ia, 1 a supernova of the type Ib or Ic. 6 among it had too low magnitudes to be able to obtain spectra.

In same time, a research similar to the CTIO (Chile): 2 deep fields out of I of 2 times 3 hours, supplemented by a research on ten less deep fields (20 minutes for the two times) in R allowed the discovery of 10 supernovæ of the Ia type whose redshifts lie between 0.32 and 1.05.

Table 7.3 summarizes the telegram of discovery published with the official name of the supernovæ, their date of discovery, their position on the sky, their magnitude in the filter of observation, their type and finally the telescope which allowed their discovery.

Table 7.3: This table presents the telegram of discovered IAU of the supernovæ discovered during the research campaign of the SCP of spring 2001. The names of the supernovæ, their date of discovery are detailed, their co-ordinates on the sky, the magnitude and the filter of their discovery, their shift towards the red, their type and the telescope which made it possible to discover them. The supernovæ marked of one $\dag$ were then followed by the space telescope Hubble.
