Dear Taichi,
 
this morning I wanted to compile a H/T sequence for U Gem using the search
facility at 
http://astro.estec.esa.nl/SA-general/Projects/Hipparcos/HIPcatalogue/
       search.html
Unfortunately I encountered some problems.
First of all, co-ordinates are for J2000.0 and not for J1991.25 as stated.
The search facility could not find data for the mag 10 GSC stars at
R.A. 07h54m24.955s  Decl. +22d22'41.16"  (J2000.0)
     07h54m20.392s        +22d16'20.53"    
     07h53m56.344s        +22d14'07.51"    
Were these relatively bright stars not observed by HIPPARCOS?
(However, I got data for a V= 11.739 star at
R.A. 07h54m59.72s  Decl. +22d20'16.520'16.5""  J2000.0)
Furthermore, the search facility could not find data for input 'HD 64813'
although this star was included in the output list for the input position
of U Gem.
 
Best regards,
Patrick
