MAX5 Phi Herculis Documentation

The file "max5ph.dat" contains the Phi Herculis observation binned data from the fifth flight of the Millimeter-wave Anisotropy eXperiment (MAX5). The analysis is described in detail in Tanaka et al. 1996, Ap. J. 468, L81 (astro-ph 9512067).

There are four bands centered at 3.5, 6, 9, and 14 cm-1. The 14 cm-1 band is included as a veto for interstellar dust; it should not be included in any CMBR analysis. Because atmospheric emission contaminated the data in the high frequency bands, we also excluded the 9 cm-1 data from our Phi Herculis analysis.

There are 12 columns and 29 rows in the file. Column 1 is not applicable to this data set. In column 4, positive is in the direction of positive azimuth. Temperatures are in antenna temperature difference units. To convert from antenna temperature differences to CMBR temperature differences, scale by

Band (cm-1) Scale
3.5 1.62
6 2.50
9 6.66
14 38.7
