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.
