Next: Polarimetric Analysis Tasks Up: Image Analysis Previous: Smoothing Images . The task imgen can be used to create an image with a source of some simple model disposition. ... It can also be used to modify an already existing image by a model. In the following example, we subtract an offset (by -1.5 and 3.5 arcsec in x and y from the reference pixel) circular Gaussian model from an image. The Gaussian parameters are given in the keyword spar (height 0.87 Jy, FWHM of 1.7 arcsec). ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

The measured position, the expected position and the offset between the measured and expected positions are calculated and written into a file. ... select catalogued positions for different observations/pointings (e.g. positions of objects in photometric sequence) . ...
