The database consists of a large number of files +representing a small patch on the sky (roughly 1.5 degree$^2$ in most +places). These files are organized into directories representing +bands of Declination. A reference file determines the coordinate +boundaries for each of the files so that a given point on the sky can +unambiguously be associated with a specific file in a specific +directory. The sky coordinates for each file is the same as those +used by the HST Guide Star catalog, except for the region around the +North celestial pole, for which all stars are included in a single +file. + +Within a given file, the data are stored in a binary format, with an +ASCII FITS-like header. The header is examply in the format of a +normal FITS header, but with the exception that all files have a fixed +number of header blocks (for now 3 blocks = 8640 bytes). This is done +to speed loading the header and finding the beginning of the binary +data. The number of 3 blocks seems quite generous, as currently only +a few FITS keywords have been defined for each file, basically +keywords to define the number of stars and the total number of +measurements stored in the file, as well as values to define the RA +and DEC range of the file. + +The first section of data following the header blocks consists of +average measurements for each uniquely observed star. Each star +occupies 20 bytes, the size of the Average structure defined above. +The Average structure contains the average Ra, Dec, and Magnitude for +the star, as well as the number of measurements, and \chisq\ values +for the magnitude and position. Finally, there is a 32 bit integer +which defines the offset to the first measurement for this star. This +offset is defined as the number of Measure records from the start of +the Measure structure. + +The second section of data, following the Average data contains all +measurements for each star listed in Average. Each measurement +occupies 13 bytes, the size of the Measure structure. This structure +contains the difference of this position from the average RA and DEC, +and the instrumental magnitude of this measurement (in the units +defined by the fstat program, which give m = -2.5*log(cts) + Mo, where +Mo is currently 24.5 [10/15]). There is also the magnitude error for +this measurement, the time of the measurement (in seconds relative to +a to-be-determined zero point), and a reference to the entry in the +Average structure so we can relate a given measurement with a given star. +This last entry also includes a byte of flags, of which only 4 have +currently been defined. This means the Average offset can only be as +large as 16,777,215 (0xffffff), limiting the possible number of stars +allowed in a given file. This does not seem like a long term problem, +though: aside from the fact that this number is very large and we +only expect in the vicinity of 20,000 stars per file, the file can +easily be divided into pieces at a later date if needed. this last +step is trivial, consisting of splitting the data up into smaller +RA,DEC regions, and updating the reference catalog. With the above +definitions for the Average and Measure structures, we will typically +expect 20,000 * 15 measurements per year and 20,000 average entries in +a given file. This implies a file size of about 4.3 MB at the end of +a year. It is also possible that we will choose to split the files up +in the future if the number of measurements makes their size +unweildy. 4.3 MB is sufficiently small that this is not a problem, +but after only 5 years, the files will be over 21 MB each, getting to +be fairly significant.

This routine does NOT try to calibrate or check +the photometry, nor does it try to improve the coordinate +determinations or calculate chisquares for position or photometry - +those tasks are performed by other routines. + +Addstar starts by loading in the photometry file and converting the +pixel coordinates to sky coordinates using the astrometry information +in the header of the file. It also gets the detection limits and +stores the image astrometry information. + +Next, addstar determines which of all the previous images overlaps +with this image and also which of the catalog regions overlaps with +this image. + +Addstar considers each catalog region in turn, and compares the +positions of stars in the catalog with stars in the image. If a +catalog star is detected, a new measurement is added to the catalog. +If a catalog star is not detected, but is in the field of view of this +image, the detection limit for this image is added to the list of +measurements as an upper limit. If the image contains a star which is +not already included in the catalog, the star is added to the catalog, +and all previous images are checked to see if they included this +location. If so, upper limits are added to the list of measurements. + +To deal with blended images, we have taken the philosophy that all +measurements compatible with the coordinates of a given star should be +included in the list of measurements. This assumes that programs or people +downstream will figure out which is the "correct" measurement. To +this end, if a catalog star is consistent with multiple measurements, +they are all added to the catalog measurement and the measurements are +given a flag to say that there was blending in the catalog (ie, it is +probably the catalog star which is a blend). If multiple catalog +stars are consistent with the same image star, that measurement is +added to each catalog star, and given a flag to say that there was +blending on the image. + +After all catalogs have been checked, updated, and written to disk, +the image is added to the database of images. + +The format for a catalog region file is as follows: + +-- +Header +-- +Averages +-- +Measurements +-- + +The Header follows the format of a FITS header but always stored with +3 blocks to speed up read time: 2880 x 3 bytes. Two important +keywords in the header: NSTARS & NMEAS + +All average values are stored consecutively in a single block. They +are written as an array with NSTARS elements of the Average structure +defined below. The individual measurements follow the averages as a +block. To find a measurement for a given star, you need to get the +value of the offset for the star. this is the element number for the +first measurement of this star, and are followed by next measurements
