基本搞定了，还有一些边角料。老外在这方面也真是挺刁的，我竟然一直没想到用他们的论文算出来的值还要加一点其它的参量，一直到看了欧洲气象中心预测的seeing图才发现seeing和涡度等有关系(汗，早就应该看出来了)。把相对涡度加进去，又加了几个二次系数，嘿嘿！出来居然和美国的GFS和CSC挺吻合的！Okay，我加了一些小改动，现在应该可以发表了。当然了，还有一点点收尾：

  • 在初步correct value上加以修改
  • 记得去掉test和check用的代码

似乎也没有了... 也应该睡觉了。

CONFIRMATIONS ON C/2006 M2 (SPACEWATCH)

  On June 20.66, 2006, C. S. Lin and Q. Ye observed an NEOCP object SW40XA, which latter proved to be a new comet, which was discovered by R. S. McMillan of Spacewatch Project, U.S.A. The discovery was annouced in IAUC 8725 and the observations were published in MPEC 2006-M27. Here are the observations of Lulin Sky Survey:
    CK06M020  C2006 06 20.65718 16 02 05.22 +02 11 15.4          20.9 N EM027D35
    CK06M020  C2006 06 20.66800 16 02 04.62 +02 11 13.7          19.7 N EM027D35
  We did not reconized any cometary appearance of the object. The object is faint, star-like, a little bit diffuse on our image. The image of C/2006 M2, taken by C. S. Lin and proceed by Q. Ye, can be view here: http://csc.lamost.org/yeiht/wordpress/index.php?page_id=140&file=Lulin%20Sky%20Survey/sw40xas001r0011.PNG.
  On June 22, J. Young and R. S. McMillan respectively used Table Moutain's 0.6-m f/16 and Kitt Peak's 1.8m f/2.7 telescope, confirmed that the object has a 4"-6" coma. The object is now 4.6 AU away from the Earth, it has passed the perihelion on late 2005 at about 5.2 AU.

2006 KX38
 
  On June 15, H. C. Lin and Q. Ye failed to do a follow-up observations for a unusual LUSS object, 2006 KX38. As the orbit published in LUSSEC 20, 2006 KX38 was a unusual asteroid with e=0.45. It's possible that this object is a comet, as Q. Ye reported it was "diffuse" (LUSSEC 15). However, the failure on follow-up prove that the orbit was bad. We should go to re-check the previous observations. The orbit is based on a 4-day observations from May 22-26.
