LQLM II DATA-TOOLS RELEASE

The second phase of the monitoring programme with the 2 m Liverpool Robotic Telescope (LRT) began in 2008 February and finished in 2010 July. This Liverpool Quasar Lens Monitoring (LQLM) II project was carried out with the RATCam optical CCD camera on the LRT, using griz Sloan  filters. The field of view and the pixel scale (binning 2 ´ 2) were ~ 4.6' ´ 4.6' and 0.278², respectively. In this almost final data-tools release, we include the frames of H1413+117 and Q0957+561 (LQLM ARCHIVE at GAVO, LRT DATA ARCHIVE or SEND A REQUEST TO US) as well as several outputs. In particular, a key subproject was the spectral follow-up of the predicted outburst in the B image of QSO 0957+561 in 2010 (ATel#2228). Apart from LRT frames of QSO 0957+561 (griz filters), we have also analyzed Swift/UVOT and Chandra exposures to properly understand the variability mechanism of the distant radio-loud quasar. This LQLM II data release also includes our two-band long-term monitoring of QSO 0957+561 (2005-2010; see below).
