 [in-profile filters](#in-profile-filters) are also available. There are three types: the `--payload` filter (a list of payloads accepted by the instance) and two range filters, `--in-range` and `--out-range`, which define the specific byte range within the stream that the instance should process. Once defined, in-profile filters apply to all subsequent instances until they are redefined. The primary purpose of these filters is to minimize relatively slow Lua calls by offloading as much decision-making as possible to the C-side code.
 
-When a packet reaches a Lua instance, the function receives two [parameters](#lua-function-prototype): `ctx` and `desync`. `ctx` provides a context for interacting with specific C-side functions. The [`desync`](#structure-of-the-desync-table) parameter is a table containing various attributes of the packet being processed. Most notably, it includes the [dissect](#dissect-structure) (the `dis` subtable) and information from the conntrack entry (the [track subtable](#the-track-table-structure)). Numerous other parameters can be inspected by executing [`var_debug(desync)`](#var_debug) or by using the pre-built [`pktdebug`](#pktdebug) instance.
