Now 8465 records in the database. Only a day or two to run now.
I've plotted some graphs in
http://www.abelian.demon.co.uk/tssp/vsd/view.html
which looks at some of the data.
Terry,
The latest estimators for Lfac:
Bare coil:
Lfac = ( 6.7487 + 4.1814 * hd) ^ -0.8837 *
( -0.002 + 1.3152 * b) ^ 0.2487 *
( 1201.8 + 19.236 * awg) ^ 0.1499 *
( 1.5699 + 4.5522 * h) ^ 0.0263 *
( 48.68 + 7.01 * sr) ^ 0.0151 + 0.6704;
rms error = 1.1%, peak error = 2.3%
Toroided:
Lfac = ( 5.53 + 5.3593 * hd) ^ -0.5883 *
( -0.0157 + 0.913 * b) ^ 0.1248 *
( 5.199 + 0.145 * awg) ^ 0.0693 *
( 3.8328 + 0.9189 * h) ^ 0.0486 *
( 5.002 + 80.761 * sr) ^ 0.0114 *
( -4.081 + 14.3399 * td) ^ 0.1629 *
( 0.3119 + 0.5798 * tb) ^ 0.0881 + 0.6773;
rms error = 1.6%, peak error = 4.5%
