... There are two types of STIS target acquisition: ACQ and ACQ/PEAK; for more details on target acquisition, see STIS ISR 97-03. ... The first is an image of the target in the target acquisition sub-array (100 x 100 pixels for POINT sources, user-defined for DIFFUSE sources) based on the initial pointing (see Figure 23.1 a), image_raw.fits[sci,1]. ... To verify that the ACQ/PEAK worked, examine the flux values at each stage of the peakup (listed in the paper products or in the data file). ...

3. Pointing error budget
Sloan Digital Sky Survey Telescope Technical Note 19970527 Walter Siegmund . ... Pointing Error Budget . ... The interleaved strips and adjacent stripes overlap about 1 arc minute. ... However, a 2-D pointing accuracy of 3 arc seconds RMS leads to acceptibly uniform overlap and minimises the number of cases that require special handling (Table 3). ... A guide fiber bundle diameter of 16.5 arc seconds and a pointing accuracy of 3 arc sec RMS results in 99% initial success in acquiring guide stars. ...

8. Standard stars
Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...
