Target Acquisition Reference Information . ... In almost all cases where an onboard acquisition will not work (because the object is in a crowded field, or is variable, or is a moving target), it is sufficient to use an early acquisition to get a WFPC2 or FOC image a few weeks in advance of the GHRS observation. ... Explicit BRIGHT and FAINT limits may be specified if you desire, although there is an increased risk of a failed acquisition unless you are confident of those fluxes. ... MAPs . ...

Accuracy Level . ... the PSF is constructed using a single bi-dimensional Gaussian fit involving energy dependent parameters which are tabulated in the CCF. This mode is a fastest way to compute the PSF but with a very limited accuracy. ... The analytical expression use to describe the PSF in the low accuracy mode is as follows. where y and z are expressed in pixels units. is the pixel size expressed in mm. ...

... The HST uses an onboard model of its orbit to perform in real-time various control functions relating to spacecraft operations and observation support. ... New coefficients for the ephemeris are updated every other day, and are archived as FITS keywords for each HST observation data set. Using these coefficients,an observer can perform a variety of calibration and characterization calculations relating to the orbital position and velocity of the telescope. ...

The reduction of a given magnitude m to it is given by: . ... The galaxy extraction was made with a Discriminant Analysis based on seven parameters (peak intensity over area, Mean surface brightness, Peak intensity, Axis ratio, Relative surface object/matrix, Elongation of the matrix and Diffraction cross) and calibrated with a sample of 1146 DENIS objects visually classified as "galaxy", "star" or "unknown". A visual inspection of every galaxy candidate was made on the matrix of pixels. ...
