This data set consists of one roll of 70-mm film containing 163 X-ray images of the sun. The data set is a subset of NSSDC data set 73-027A-05A, and it is intended to provide a series of synoptic views of the X-ray sun at approximately 24 h intervals. The filter/exposure combination was chosen to optimize the data for use in studies of coronal holes and other coronal structures, which vary on time scales of days or longer. All images are taken in filter 3 (disjointed passband of 2 to 32 A and 44 to 54 A), with 64-s exposure times. Each frame includes the white-light image taken prior to the X-ray exposure, since the corresponding white-light image is offset on the film. The date of each frame and its location on the film are listed next to each frame. Orientation is best accomplished by laying the X-ray image over a hydrogen alpha image of the sun. The documentation cross-references the frame location, the date and time, and the frame number in the film image catalog (data set 73-027A-05B).
