shows the text Reading PEC Table… while the data is being retrieved from the Bisque TCS.
Remove the PEC Table from Telescope Control System (Clear Button)
Click the Clear button to permanently remove the PEC table stored in the Bisque TCS non-volatile memory. The
PEC Table graph shows the text Clearing PEC Table… while the data is being deleted from the Bisque TCS.
Paste PEC Table (Paste Button)
Click this button to retrieve the periodic error correction table values that have been previously copied to the
Clipboard and graph them in the PEC Table.
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 PEC table index.
• 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
The number in the first column is the PEC table index that represents a relative position of the worm. The second
column in the table is the periodic error at that position.
