SIS Background - Blank Fields
These sequences have been checked by eye, and divided into CCD modes. This list contains blank, or near-blank, fields observed between 1996 and the end of mission. (We plan to complete the list back to the launch in due course.)
In the comment field below, "F/B" refers to sequences in which Faint mode was used at High bit rate, Bright mode at Medium bit rate. Others were all taken in Faint mode.

2-CCD Mode
Active chips are indicated in the comment in the form kl/mn, meaning S0Ck and S0Cl, and S1Cm and S1Cn were used.
