Dear VSNET members,

Hello. I am Seiichi Yoshida working on the MISAO Project. Now I
introduce you the examination result of sn1998eb.jpg introduced us in 
[vsnet-chat 1328].

http://ftp.kusastro.kyoto-u.ac.jp/pub/vsnet/SNe/sn1998eb/sn1998eb.jpg.

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:

First of all, I deleted the letters and line to point out the
supernova on the image using Photoshop, and then I examined it by the
PIXY system.

This image is of SN 1998eb. But the system could not detect the
supernova. Magnitude estimation of the supernova by hand is 17.9 mag.

Although the system could detect two bright stars left of the galaxy,
but they are not recorded in the USNO-A1.0 because being blended in
the galaxy. No other remarkable objects were detected in this field.

The photometric data of the galaxy is quite uncertain.
