Notes. CA22: 2.2~m telescope at Calar Alto Observatory, using CAFOS
with a $2{\rm k}\times2{\rm k}$ SITe pixel CCD; WS: 0.8~m
telescope at Wendelstein Observatory, using the MONICA CCD camera
\citep{roth90-1}; OLT: 1.2~m Oskar L\"uhning Teleskop at Hamburg
Observatory, equipped with a $1{\rm k}\times1{\rm k}$ pixel SITe
CCD; INT: 2.5~m Isaac Newton Telescope on Observatorio del Roque de
los Muchachos, equipped with the Wide Field Camera (WFC), an array of
four EEV $2{\rm k}\times4{\rm k}$ pixel CCDs; KY: 1.2~m
telescope at Kryoneri Observatory, using a Photometrics SI-502
$516\times516$ pixel CCD camera; IAC80: 0.82~m telescope at
Observatorio del Teide, equipped with Thomson
$1{\rm k}\times1{\rm k}$ pixel CCD camera; OGS: 1~m Optical
Ground Station at Observatorio del Teide, equipped with Thomson
$1{\rm k}\times1{\rm k}$ pixel CCD camera; AIP: 0.7~m telescope
of the Astrophysikalisches Institut Potsdam, using with
$1{\rm k}\times1{\rm k}$ pixel SITe CCD; FLWO: 1.2~m telescope
at Fred Lawrence Whipple Observatory, equipped with the 4-Shooter CCD
camera, an array of four $2{\rm k}\times2{\rm k}$ pixel, and only a
small part of the CCD\#3 was read out; BS: 0.41~m at Braeside
Observatory telescope, using a SITe $512\times512$ pixel CCD camera;
the comparison stars used in instrumental magnitude extractions from
Braeside are unknown (marked by colons).
