... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

Collection of the orbital elements | ... The errors of the spacecraft motion extrapolation outside the measuring time interval were estimated by using the comparison of SC positions calclulated by the forward integration ( extrapolation method) and backward integration ( interpolation methods). ... The character of these time shift of the ascending nodes ( D Tn) corresponds to the orbiting period errors, which arise during SC motion extrapolation outside the measuring intervals. ...

We have produced a high-level overview of PROS. ... The incremental stages were the short-term goals: a project overview diagram (i.e., an organizational diagram of software modules); high-level diagram (i.e., a bubble diagram of each module in the system); and unifying element tables (i.e., tables of task vs. software attributes)....

The azimuth has an encoder on each side of the encoder rack gear. encoder 1 is on the dome side and is used for pointing the telescope. encoder 2 is on the ch side and is used to measure the bending of the azimuth arm.

The correct position for the pointer on the reference mark is whereever it was when the last pointing model was made. ... az encoder error . ... new encoder in position (.jpg) .3 mm left of center mark . ...

Since an encoded file is an ASCII file, you can edit it to change the access permissions and file label. The first line of an encoded file might be: begin 600 pictures.tar.Z . The number 600 defines the access permissions for the original file - which the decoded file will also have. ... To change the access permissions edit the number 600 to something more appropriate such as 644 and then save the file. You can change the file label in the same way. ...
