Space photometry with HuPhot

HuPhot has for main goal the measurement of fluxes of supernovæ observed with camera WFPC2.

We will initially present the methods and the performances of the estimates of flux of HuPhot for two types of photometry: the photometry of opening and the optimal photometry given by equation 8.4 .

Then, we will present the various corrections which must be made to these measurements of flux.

Lastly, we will approach the estimate of the photometry of the supernovæ by differential photometry after having described the constraints related to the observations.
