The RawPy class provides the main interface for reading and processing raw image files. This section documents the public members of the class, excluding the low-level methods listed separately.

```APIDOC
## RawPy class

### Description
The RawPy class is the primary interface for working with raw image data. It provides methods for opening, unpacking, and processing raw files, as well as accessing image metadata and pixel data.

### Members
- `__init__` - Constructor for the RawPy class.
- `open_file` - Opens a raw image file. (Note: This method is listed as a low-level method and is documented separately.)
- `open_buffer` - Opens a raw image from a buffer. (Note: This method is listed as a low-level method and is documented separately.)
- `unpack` - Unpacks the raw image data. (Note: This method is listed as a low-level method and is documented separately.)
- `unpack_thumb` - Unpacks the thumbnail image. (Note: This method is listed as a low-level method and is documented separately.)
- `dcraw_process` - Processes the raw image using dcraw. (Note: This method is listed as a low-level method and is documented separately.)
- `dcraw_make_mem_image` - Creates a memory image from the processed raw data. (Note: This method is listed as a low-level method and is documented separately.)
- `dcraw_make_mem_thumb` - Creates a memory thumbnail from the processed raw data. (Note: This method is listed as a low-level method and is documented separately.)
- Other public members as documented by the autoclass directive.

### Notes
- The methods `dcraw_make_mem_image`, `dcraw_make_mem_thumb`, `dcraw_process`, `open_file`, `open_buffer`, `unpack`, and `unpack_thumb` are excluded from this section and documented separately as low-level methods.

These are additional low-level methods of the RawPy class that provide direct access to dcraw functionality and file/buffer operations.

```APIDOC
## Additional low-level methods

### Description
These methods are low-level interfaces to the underlying dcraw library and provide direct control over file opening, buffer reading, unpacking, and processing.

### Methods

#### `open_file`
Opens a raw image file.

#### `open_buffer`
Opens a raw image from a memory buffer.

#### `unpack`
Unpacks the raw image data.

#### `unpack_thumb`
Unpacks the thumbnail image.

#### `dcraw_process`
Processes the raw image using dcraw.

#### `dcraw_make_mem_image`
Creates a memory image from the processed raw data.

#### `dcraw_make_mem_thumb`

### rawpy.enhance.find_bad_pixels()

Source: https://letmaik.github.io/rawpy/api/rawpy.enhance.html

Finds and returns coordinates of hot/dead pixels in the given RAW images. The probability of correct detection increases with more input images, which should be taken around the same time and with movement between shots.

Also, there should be movement between the images to avoid the false detection of bad pixels in non-moving high-contrast areas.

### Method
Function call

rawpy.enhance.find_bad_pixels(paths, find_hot=True, find_dead=True, confirm_ratio=0.9)

### Parameters
