Description:
    The observations presented in table 3 were made by using the 1.03m
    Dall-Kirkham-type telescope (f/8.45) of Tuorla Observatory with a SBIG
    ST-8 CCD-camera and a standard V-band filter. Table 4 includes data
    (B-, V- , and R-bands) observed at the Nordic Optical Telescope (NOT)
    on La Palma.

    Corrections for dark-current effects, additive effects (bias) and
    multiplicative effects (flatfield) were applied. Due to the relatively
    small field of view of the telescope separate frames of comparison
    stars were exposed for Mrk 421 and 4C 29.45. For the other objects
    normal differential photometry methods were applied. Exposure times
    with the Tuorla 1.03 meter telescope were between 60 and 240 seconds
    for objects brighter than 16 mag. For fainter objects, we have
    combined several exposures to achieve a sufficiently high signal to
    noise ratio.
