121 Summary: 

122 Specify the names of the data files and MeasurementSet 

123 

124 Description: 

125 

126 

127 This function does the actual filling of the data from rpfits format 

128 files to a MeasurementSet. After the completion of the fill operation 

129 you should call the done method to avoid problems with incomplete 

130 flushing of the data to disk. You may want to run select before fill, to 

131 reduce the amount of data you read in. 

132 

133 In the filenames argument commas are not allowed because of the 

134 wildcard capability. 

135 

136 The options argument allows for special processing options during the 

137 filling process. 

138 

139 * birdie: remove self generated birdies in 128 MHz 

140 data by deleting every other channel and the edge 

141 channels 

142 * reweight: suppress ringing of interference spikes by 

143 reweighting the lag spectrum for minimum spectral sidelobe response 

144 * noxycorr: do not apply the xyphase 

145 correction using the noise cal xy phase measurements (use if you 

146 know there was a problem with the measurements) 

147 * compress: Compress the data, model, corrected data and imaging weight 

148 columns (may reduce dynamic range) 

149 * fastmosaic: Produce a MeasurementSet with small tiles to optimize I/O 

150 for observations with a large number of pointings and a short time (a few 

151 integrations) on each pointing. Failing to use this options for such data 

152 may cause very inefficient access, especially for continuum data 

153 (10-100 times slower) 

154 * hires: For data taken in binning mode: set the TIME_CENTROID column to 

155 the center of each bin (normally center of integration interval). The TIME column is 

156 unaffected. TIME_CENTROID will no longer be in time order for dual frequency 

157 mode. 

158 * noac : Do not load the autocorrelations 

159 

160 Input Parameters: 

161 msname Filename for MeasurementSet to create  

162 filenames Existing RPFITS files to read; wild cards accepted, don't use commas  

163 options Processing options: birdie, rfiflag, noxycorr, compress, fastmosaic, hires, reweight, noac

233 Description: 

234 

235 

236 

237 Select on various items, to load only a subset of the data present in 

238 the input file. The default is to load everything. 

239 Note that the frequency selection using lowfreq and highfreq acts purely on 

240 center (reference) frequencies, channel selection is not available at this stage. 

241 Use freqchain to select the frequency chain (or IF) to load, 

242 specify either 1 or 2, the default of zero will load both. 

243 Use the fields parameter to specify a list of field names (sources) you 

244 want to load. 

245 For detailed selection of complex observations the last two parameters let 

246 you specify the required bandwidth (in whole MHz) and number of channels 

247 of the first frequency chain. 

248 

249 Input Parameters: 

250 firstscan First scan to read 

251 lastscan Last scan to read 

252 spw Select one or more spectralwindows , -1=all  

253 lowfreq Lowest reference frequency to select 

254 highfreq Highest reference frequency to select 

255 fields List of field names (sources) to select  

256 edge Percentage of edge channels to flag
