They are measurements carry out with filters but without calibration
The filters are filters SCHOTT whose composition is:
V (SCHOTT) GG495 (2mm) + BG18 (1mm) + WG305 (1mm)
R (SCHOTT) OG570 (2mm) + KG3 (2mm)
N (SCHOTT) NG12(4mm)
Measurements with the filter R and filter N (neutre): comparison 20 stars
USNO SA2.0
Measurement with the filter V : comparison with 20 stars GSC
Software : PAPv4b15
Soon, we will gauge on stars of M67,M92,Ngc7790 or fields "LONEOS"
