Dear VSNET members,

Hello. I am Seiichi Yoshida working on the MISAO Project. Now I
introduce you the examination result of the image of (SN)1998di,
sn1998di.fts taken by Dr. Schwartz.

These data are automatically measured by the PIXY system, an automatic 
image examination software, of the MISAO Project. Reference catalog is 
USNO-A1.0 (V) [V=R+0.375(B-R)]. False data removal and identification
verification have been done by hand after all. For more information
about the project and the system, please see the URL:

http://www.info.waseda.ac.jp/muraoka/members/seiichi/misao/

The output view of the PIXY system is available at:

http://www.info.waseda.ac.jp/muraoka/members/seiichi/misao/tmp/vsnet/sn1998di.gif

The data of 1998di is:

19 24 38.22 +59 41 47.2  mag=16.5  x=  71.15  y= 268.48
  1998di  19h24m38s.19  +59o41'46".7  16.8 mag  type:(dn)   Aug. 2  M. Schwartz

The positional difference from IAUC data is 0.6 arcsec.

Unfortunately, the arm of a galaxy MCG+10-27-012 was detected, as a
red star plotted in "Detected Stars" chart (sn1998di.gif).

This faint object is an anonymous galaxy.

19 24 19.33 +59 38 09.3  mag=17.2  x= 188.84  y= 441.75
  USNO1425.09788959   19 24 19.28  +59 38 08.9  16.1 R  17.2 B  (16.51V)
  USNO1425.09788999   19 24 19.46  +59 38 09.4  17.0 R  18.0 B  (17.38V)

The three stars which are not in USNO are all near by another star. So 
the data in USNO are probably blending.
