In the 1990s, measurements of both standard red giants as well as red clump stars from the Hipparcos satellite measurements were used to calibrate the Cepheid distances.

Good critics, who have stamped out poet’s hopes;
Good statesmen, who pulled ruin on the state;
Good patriots, who, for a theory, risked a cause;
Good kings, who disembowelled for a tax;
Good Popes, who brought all good to jeopardy;
Good Christians, who sat still in easy-chairs;
And damned the general world for standing up.—
Now, may the good God pardon all good men!”
