This directory contains details on the discovered Blue Large-Amplitude
Pulsators (BLAPs). The directory structure is as follows:

INFO              - this file

blap.dat          - observational parameters of the variables

fcharts/          - finding charts for individual objects

phot/             - photometry of individual objects in the format:
                    BJD_TDB-2450000, mag, magerror

spectra/          - normalized spectra of some variables in the format:
                    lambda[Angstrom], normfluxobs, normfluxfit


Finding charts are gzipped Postscript images. The charts are 60"x60"
subframes of the I-band reference frames centered on the star.
White cross marks the star. North is up and East to the left.
