Optical Filters . The WFPC2 camera configuration and filter set require a substantial number of apertures for full utilization of its capabilities. ... An additional set of aperture names have been defined for use with the WFPC2 filters which require partial rotations. ... The pixel coordinates of these apertures will be reviewed on a regular basis to reflect changes in CCD and filter cosmetics. ... The aperture name is generally the same as the (rotated) filter name. ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

... The procedure simply observes ON your source for x minutes and then takes a `blank sky' observation OFF your source for the same amount of time and tracking the same azimuth and zenith angle range. ... Typically, observing times are kept to within 5 minutes (with 5 minutes as the most efficient, and therefore default, choice). ... If your scans are for 5 minutes or less, your wait time should be set to 1 minute (the default setting). ... A 5 minute ON/OFF + 10s CAL takes 11.3 minutes. ...

... 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 first of the equations defines the position of the spectral orders, m , in the raw image, while the second equation gives, for each order, the dispersion relation in one dimension. ... where the coefficients are computed using least squares techniques on a grid , i.e. sample number and line number of points located within the spectral orders of the image. These points in the grid are found automatically by an order--following algorithm, normally using the FLAT or STD image. ...

... The spectroscopic model of the source gives , the number of photons received per cm and per second at the earth, from sky position and at energy (differential per solid angle and energy). The number of photons, , detected (per second) in pixel and in PI energy bin centered at is obtained by multiplying by the effective area and applying the response matrix: . ... The correspondence between sky position and detector coordinates depends on the telescope's pointing. ...
