|
|---|
| 10 | Recently, Mr. Barry N. Rappaport of New Mexico State University
|
|---|
| 11 | transcribed the constellation boundaries as fixed by the IAU into
|
|---|
| 12 | machine-readable form. These have been transcribed by Dr. Nancy G.
|
|---|
| 13 | Roman to make it possible to determine by computer the constellation
|
|---|
| 14 | in which a position is located.

|---|
| 623 | INPUTS
|
|---|
| 624 | r right ascension, radians
|
|---|
| 625 | d declination, radians
|

| 626 | e epoch to which r and d precessed, as an mjd
|
|---|

|
|---|
| 628 | RESULTS
|
|---|
| 629 | Returns an index for the constellation region that the coordinates
|
|---|
| 630 | belong to, or -1 if no constellation pick can be found.
|
|---|
| 631 |
|
|---|
| 632 | The constellation is identified by linear search. We look for a
|
|---|
| 633 | member of cbound[] whose lower_dec is less than the declination of the
|
|---|
| 634 | pick point and whose lower_ra and upper_ra bracket the pick point's
|
|---|
| 635 | right ascension. The data for that cbound[] member describes a sub-
|
|---|
| 636 | region belonging to the picked constellation.
|
|---|
| 637 |
|
|---|
| 638 | In geometric terms, the search amounts to starting at the north pole
|
|---|
| 639 | and traveling south on a line of constant right ascension through the
|
|---|
| 640 | pick point. At every declination where a cbound[] member lives, we
|
|---|
| 641 | wake up, and if (1) the pick point is now behind us, and (2) the
|
|---|
| 642 | cbound[] segment is crossing our path, we know we've hit the edge of
|
|---|
| 643 | a constellation subregion that the pick point belongs to.
|
|---|
| 644 |
|
|---|
| 645 | The cbound[] right ascension and declination values are scaled into
|
|---|
| 646 | integers; this conserves storage and makes comparisons faster. The
|
|---|
| 647 | start[] array, which gives starting points in cbound[] for different
|
|---|
| 648 | declinations in 5-degree increments, further speeds the search by
|
|---|
| 649 | skipping early parts of the list for which we know the search can't
|
|---|
| 650 | succeed--geometrically, we start no more than 5 degrees north of the
|
|---|
| 651 | pick point, rather than at the north pole.
|
|---|
| 652 |
|
|---|
| 653 | The data in cbound[] are for epoch 1875.
