- "As mentioned earlier, there are three types of cutout services. Demonstrated above in Section 3 is the `cutout-sync-exposure` service that returns an `ExposureF` type image with all LSST image extensions. The `cutout-sync-maskedimage` service that returns an `MaskedImageF` type containing the LSST image, variance, and bitmask. But, unlike `ExposureF`, the `MaskedImageF` is missing the full range of metadata that may be needed to perform science on the images, including the WCS model and bounding box, the photometric calibration and physical filter used, optical models including the PSF and aperture correction map, telemetry and detector. \n",
