The rotation of the stellar component of galaxy is obtained from the compilation of internal stellar kinematics . The rotation of the gaseous component is given in the parameter vmaxg , and the stellar velocity dispersion in vdis . For disk-like galaxies (eg. mostly disks of spiral), the apparent rotation may be converted into the true (physical) rotation using the inclination given in the parameter incl . HyperLeda .

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 . ...

... An estimate the rotation period of cometary nuclei is important for understanding and describing the physical processes of the cometary activity. Unfortunately, the measurements of the rotation periods of the comet nucleus depend on the model assumptions and it is one of the main reasons for the scatter of the estimates given in various articles for a given comet. ...
