1. Observing with Linear Ramp Filters
... The Linear Ramp Filters provide a narrow band ( ) imaging capability which is continuously tunable from 3710 to 9762 . ... If it is necessary to know which CCD will be used, observers can consult Table 3.7 on page 48 or Table 3.8 on page 49 , or use the on-line LRF calculator tool on the WFPC2 WWW pages. It is possible to use POS TARGs with LRF observations; the offsets are made from the default pointing for the specified wavelength. ... POS TARG "X" = -0.09961 (235.7-414) = 17.76" , and . ...

4. What was measured?
... An OBJECT column gives the name of the object observed (usually a star name). ... In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...

6. Algorithm
... Up: Description of program searchdup Previous: Program use . Input records are ordered per date of observation, and the list of known (observed) sources is cleared. Each record is compared in position to all the known sources. If the sky distance is less or equal to the specified one, the record is added to the list of observations for that source. If no known sources are within the specified radius, a new source is created, with the coordinates of the observation record. ...

11. Accuracy of World positional CCD observations of the numbered minor planets
... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...
