An online version of this catalogue can be seen here. I wanted to use this catalogue to confirm that the stars I have referred to as X and Y in the field of the variable star Z Ursae Majoris aren't variables in themsleves. This would pose a problem to using them as comparison stars if they were.
Star X is HIP57820 and is also known as HD102956 or Aniara. If you click on the GCVS query form you can use the cross-identification to select the HIP (Hipparcos) catalogue and enter the number 57820. No record is found which I take to mean that this star is not a variable.
The same can be said of star Y which is HIP58302 also known as HD103810. Now Z Ursae Majoris is HIP58225 and this brings up the record for this variable star.
