In the following pages we
outline photometry tecniques and photometric diagrams usage, normally involved
in deriving fundamental parameters for open cluster members:
Medium
open cluster reddening value <E(B-V)>, using CCD
/ TCD diagram and the sliding-fit technique
Individual
reddenings E(B-V)ind of early type stars on CCD / TCD,
using both reddening lines method and Johnson Q
method
Medium and late type
stars individual reddenings using E(B-V), B(0)technique
Determination of dE(B-V)
in presence of elevated cluster non uniform reddening using CCD / TCD diagram
and sliding-fit technique
Zams-Fitting
method and Color-Magnitude (CM) diagram
Determination of cluster
<Vo-Mv> true medium distance moduls using Zams-Fitting
method on a CM diagram
