A supernova remnant (SNR) is an expanding shell of gas that results from the explosive death of a star. When observing a SNR at radio wavelengths, the object appears fainter in the higher frequencies and brighter in the lower frequencies due to synchrotron radiation. There has not been a complete catalog of SNRs in the Large Magellanic Cloud (LMC), shown in Figure 1. As a result, in May 2017, Luke M. Bozzetto and Miroslav D. Filipović et. al published an article with a catalog of 59 SNRs, using their own measurements and references of other data. Their paper also proposed 15 SNR candidates, all located in the LMC. Their measurements focused on the radio properties of these objects. One of these properties is the spectral index, which is the brightness as a function of frequency, and is shown in Figures 4 and 5. However, some of the objects cataloged and proposed have missing radio data. Using the Astronomical Image Processing System (AIPS) and data previously collected by John R. Dickel, we analyzed the missing radio data for these objects cataloged in the 3- , 6- , and 20- cm radio wavelength bands.
