Copy Custom PEC Table (Copy Button)
Click this button to copy the current periodic error correction table values from the graph to the
Clipboard in ASCII text format. The format of the ASCII text data is two space delimited columns:
•
the zero-based table index (0-999 for the Paramount MX, 0-1249 for the Paramount ME)
•
the relative mount-specific periodic error correction.
Column values must be separated by a minimum of one space character (no tabs), with carriage return
line feed pairs at the end of the line.
The following text shows an example ASCII PEC table.

PEC Table Index
This value shows a number (1-1000 for the Paramount MX or 1-1250 for the Paramount ME) that
represents the position of the worm in the table of PEC corrections.
Compute PEC Curve Tab
The Paramount’s (ME and MX) periodic error
specification
is a maximum of 7 arcseconds peak to peak
periodic error
before
periodic error correction. The
actual
periodic error of most Paramount mounts
before correction is around 3.5 arcseconds peak to peak. The difference between the mount's actual
periodic error and the specified periodic error can be caused by minute variations in the mount's
internal components (gears, worms, pulleys, belts, etc.).
