Examples of spectroscopic snapshot images produced by SIMPL in its default mode. All images are generated using 1 s integration and 195.3 kHz frequency averaging, except for panel d, which was integrated over 1 s and 1 MHz. Contours are drawn at 3%, 5%, 10%, 20%, 30%, 50%, 70%, and 90% of the maximum intensity in each image. The red ellipse in the bottom-left corner of each panel indicates the restoring beam, and the dashed cyan circles represent the optical solar disc. Top panels a–c: HBA observations. Panels a and c show examples of noise storm emission. Panel b displays a bright type III radio burst, more than an order of magnitude more intense than the noise storm in panel a. Low-level contours reveal the quiet Sun emission even in the presence of strong radio sources. Bottom panels d–f: LBA observations. Panel d shows a quiet Sun snapshot at 35.64 MHz with a dynamic range of 104. Panels e and f correspond to snapshots immediately before and during a type II burst. The quiet Sun remains visible in the low-level contours, even in panel f, despite the presence of an intense burst.
