Figure 4: The stars that were chosen for relative photometry in the investigation of the secular decrease in luminosity. The numbering is the same as in Table 4 where the UBVRIz magnitudes for these stars are given. The numbering is also used in Table 3. The pulsar is number eight. This V-band image was acquired with the JKT on February 7, 1990. North is up and east is to the left. The field of view is approximately 3.2 by 2.1 arcmin. |
