 ## Expression syntax
 
-Use `{COL_FUNCTION}("name")` to refer to rawdata columns (e.g. `col("a")`).
 Expressions are unit-aware and units are taken from column metadata.
 
 Mathematical operations:
-- Operators: `+` `-` `*` `/` `**` `%`
-- Functions: `sin(x)`, `cos(x)` (argument must be an angle), `str(x)`, `to_deg(x)`
-- `to_deg(x)` parses coordinate strings or converts angle quantities to degrees
+- Operators: {operators}
+- Functions: {functions}
 - Numbers are dimensionless
-- String literals and `+` concatenation are supported
-- Modulo divisors must carry units (e.g. `col("pa") % (180 * deg)`)
+- String literals are supported
 - Log columns (`mag`/`dex`) yield the bare exponent; multiply by the scale yourself
 
 Available constants: {constants}.
