work in progress

notes:

• we only care about stripe 82:

306° < ra < 62°
-1.27° < dec < +1.27°

• the source data only comes sorted by dec, so we want to start with these two files:

  • http://irsadist.ipac.caltech.edu/wise-allwise/wise-allwise-cat-part25.gz - -1.861900 < dec <= 0.746200
  • http://irsadist.ipac.caltech.edu/wise-allwise/wise-allwise-cat-part26.gz - 0.746200 < dec <= 3.357000

• then we want to import those two files into dat with a filter like this:

  • -1.27° < dec < +1.27° && 306° < ra < 62
  • then we know we only have data in stripe 82

• import scripts:

cat wise-allwise-cat-part25.gz | gunzip | csv-parser --headers=$(cat columns.tsv) --separator="|" | jsonmap "{ra: +this.ra, dec: +this.dec, key: this.source_id}" | jsonfilter --match="(306 < this.ra && this.ra < 360 && 0 < this.ra < 62) && (-1.27 < this.dec && this.dec < 1.27)" | node index.js
