VizieR Online Data Catalog: Intensive monitoring of OJ 287 (Pursimo+, 2000)

We present intensive optical, infrared, and radio monitoring observations of the BL Lac object OJ 287, taken between the years 1993-1998. Most of the optical observations were taken using CCD-cameras and the data were reduced using standard procedures, i.e. bias and flat field corrections. For these data differential photometry was performed using calibration stars (4,10,11) from (Smith et al. 1985AJ.....90.1184S) or Fiorucci & Tosti (1996A&AS..116..403F, Cat. J/A+AS/116/403).

All the optical polarisation observations were made using similar UBVRI photopolarimeter both at Crimea and at the NOT. The infrared data were collected mostly at the 1.5m Carlos Sanchez telescope on Tenerife, using a single channel CVF-photometer with some additional data from UKIRT.

The radio data are nightly averages collected within radio monitoring programs at Michigan, Metsahovi, and SEST, with frequencies from 4.8 to 230GHz.

Small amount of UV data was obtained with the IUE-satellite during the first outburst.

In addition we provide visual brightness estimates from amateur astronomers.
